Parking brake system on a car Skoda Rapid, equipped with rear drum mechanisms, inevitably loses its effectiveness over time. This is due to natural wear of the brake linings and stretching of the cable drive. If the handbrake lever has to be raised 7โ9 clicks or more, and the car is difficult to hold on a slope, immediate diagnosis and adjustment is required.
Many owners mistakenly believe that the problem can be solved solely by tightening the cable under the bottom, but Skoda Rapid The root cause is often wear on the pads themselves or jamming of the mechanism. Incorrect settings can lead to overheating of the drums or, conversely, to a complete lack of fixation. In this article we will look at two main ways to restore the system's functionality: adjustment through a cable and adjustment through an eccentric.
Preparation for work and necessary tools
Before you begin dismantling the wheels and removing the brake drums, you need to make sure that you have a complete set of tools on hand. For quality maintenance work Skoda Rapid you will need a standard set of wrenches, 10, 13 and 17 mm sockets, as well as a specialized brake pad release tool.
Safety is the number one priority when working on suspension and braking systems. The car must be parked on a level surface, first gear is engaged and wheel chocks are placed under the front wheels. If you plan to lift the rear of the car, use secure jack stands rather than just a jack.
- ๐ง 10 mm wrench to remove the protective cap on the cable
- ๐จ Hammer and chisel (or drift) to drive out the drum locking pin
- ๐ฉ A key for adjusting the eccentric (a screwdriver or a special key is often used)
- ๐งผ Brake cleaner and wire brush for cleaning surfaces
Be sure to check the condition of the drive cables before starting work. If the cable sheath is damaged or the cable itself has signs of corrosion, simple adjustment will not help and a complete replacement of the kit will be required. On Skoda Rapid the cables run from the lever to the rear axle and are often exposed to reagents.
Diagnostics of the condition of brake mechanisms
The surest way to understand why the handbrake does not hold is to remove the brake drum and visually assess the wear of the parts. On Skoda Rapid With drum brakes, the pads wear unevenly, and sometimes the lining wears down to metal without causing any extraneous sounds, since the mechanism is hidden inside.
Remove the wheel, unscrew the two drum guide pins (usually they require a 10 or 13 mm wrench, sometimes they need to be knocked out carefully with a hammer). Remove the drum, making sure it is not jammed. If the drum is difficult to remove, try tapping it lightly through a piece of wood, but do not use excessive force to avoid damaging the seats.
- ๐ Inspect the thickness of the brake linings - it should not be less than 1.5 mm
- ๐ Check the condition of the drum for deep grooves and cracks
- โ๏ธ Evaluate the operation of the return springs - they should not be stretched or broken
If you see that the pads are critically worn, tightening the cable will only temporarily solve the problem and may lead to the wheel jamming. In this case, it is necessary to replace the brake pads. It is important to note that on Skoda Rapid Rear brakes often have a built-in slack adjuster mechanism that can seize.
โ ๏ธ Attention! If, when removing the drum, you see that the pads have been ground down to a metal base, it is strictly forbidden to operate the car until they are replaced. Metal on metal will destroy the drum, leading to costly repairs.
Sometimes the problem lies not in the pads, but in the release mechanism. The shoe drive lever, on which the cable presses, may have play or rust at the attachment points. Clean all moving parts, lubricate them with high-temperature grease, but do not allow the grease to come into contact with the friction linings.
Adjustment via cable tension
If the pad wear is within acceptable limits, the first step is to adjust the parking brake cable tension. This procedure is performed in the engine compartment or under the bottom of the car, depending on the year of manufacture Skoda Rapid. Typically the adjusting nut is located under the center tunnel, next to the gear shift lever.
You need to loosen the lock nut and rotate the adjusting nut clockwise to tighten the cables. Do this evenly until you achieve the desired resistance. Do not over-tighten the cable, otherwise the rear wheels may start to brake even with the lever lowered, which will lead to overheating and rapid wear.
- Only by cable
- Only eccentric
- Comprehensively
- I don't know
After pre-tightening, check the result. Raise the handbrake lever and count the number of clicks. For Skoda Rapid 4-6 clicks at full tension is considered normal. If there are more clicks, repeat the tightening procedure. If less, loosen the nut.
- ๐ Check if the wheels are locked after adjustment
- ๐ Measure the travel of the handbrake lever (should be within 4โ6 divisions)
- ๐ Make sure the vehicle is securely supported on a 15-20% incline
This method is effective if the cables are not stretched critically. Otherwise, even after fully tightening the adjusting nut, you will not achieve the desired effect, since the cable will simply stretch even more during the first use. In such cases, replacement of the cable drive is required.
โ๏ธ Checking the cable tension
Adjustment via eccentric mechanism
The most reliable way to set the handbrake to Skoda Rapid - this is adjusting the gap between the pads and the drum through a special eccentric. This mechanism is located inside the brake assembly and allows you to move the pads apart, compensating for their wear without unnecessary cable tension.
To access the eccentric, remove the brake drum. On the side of the back of the brake shield you will find a rubber plug. Remove it and you will see a hole through which the adjustment mechanism is accessible. By rotating it with a special screwdriver or wrench, you change the position of the pads.
You need to rotate the eccentric in the direction that moves the pads apart. Usually this is a clockwise rotation, but it is better to check by ear: when the pads touch the drum, you will hear a characteristic grinding sound. After this, turn it back 1-2 clicks to ensure minimal clearance.
โ ๏ธ Attention! When adjusting through the eccentric, make sure that you do not distort the mechanism. If after assembly the drum does not fit on or rubs against the pads, then the gap is set incorrectly and will require re-disassembly.
After adjusting both rear wheels, reassemble the assembly in reverse order. Reinstall the rubber plugs to prevent dirt and moisture from getting inside. Then check the operation of the handbrake: it should work smoothly, without jerking, and hold the car with a minimum number of clicks.
The nuances of replacing the eccentric
If the mechanism is jammed and does not turn, do not use brute force. Try generously lubricating it with penetrating lubricant (WD-40) and leave it for 15-20 minutes. If this does not help, you may need to replace the entire brake shield or regulator mechanism, since restoring a jammed eccentric is often impractical and unreliable.
Eliminating jammed cables and levers
A common problem on Skoda Rapid - this is the jamming of cables inside the sheath due to moisture and dirt. Even if you adjust the tension correctly, a jammed cable will prevent the pads from returning fully to their original position, causing constant drag.
Check the cable movement manually. Disconnect the cables from the lever on the rear axle and try to pull them. They should move easily, without jamming. If resistance is felt, the cable must be replaced. Also check the levers on the pads themselves - they should move freely at the attachment points.
- ๐ง Treat the entry points of the cables into the sheath with penetrating lubricant.
- ๐ Check the movement of the lever on the brake shield
- ๐ฉ Inspect the cable fastenings to the body for corrosion.
In some cases, dismantling the cable, washing it and then lubricating it with graphite lubricant helps. However, on modern cars Skoda Rapid cables often come in a permanent sheath, so replacement is a more reliable solution to the problem. Do not try to lubricate the cable inside the sheath through small holes - this is a temporary measure.
Pay special attention to the place where the cable is attached to the parking brake lever in the passenger compartment. There may be corrosion or wear where the cable contacts the lever. If there is too much play, the lever will move sluggishly and braking performance will be reduced.
Before installing new cables, be sure to treat them with silicone grease on the outside and inside, if the design allows. This will extend the life of the new set and ensure smooth running of the mechanism in the future.
Check and final assembly
After completing all manipulations with cables and eccentrics, a thorough check must be carried out. Reinstall the wheels, lower the vehicle and test drive. Accelerate to 40 km/h and gently press the brake pedal, then check to see if the rear wheels are heating up.
Put the car on the handbrake on a slope and check that it is securely held. The lever must be fixed clearly, and the car must not roll away. If everything is in order, tighten all nuts and bolts to the recommended torque.
| Parameter | Normal value | Permissible deviation |
|---|---|---|
| Handbrake lever travel | 4โ6 clicks | 3โ7 clicks |
| Pad thickness | more than 2.0 mm | minimum 1.5 mm |
| Cable play | missing | up to 1 mm |
| Drum temperature | warm | not hot to the touch |
The first couple of times, press the lever all the way 5-10 times to grind the pads to the drum.
โ ๏ธ Attention! If, after adjusting the handbrake, the rear wheels still become very hot after driving, stop immediately and check the clearance. Overheating can lead to deformation of the brake disc (if there was one) or destruction of the drum.
Complete assembly by ensuring that all cable and drum protection caps are in place. This will prevent moisture and dirt from entering the mechanism, which is especially important during winter operation. Skoda Rapid.
Adjusting the handbrake via an eccentric provides more accurate clearance and durability of the brake system compared to simply tightening the cable, but requires more time and disassembly of components.
Frequent maintenance errors
Many owners Skoda Rapid make typical mistakes when trying to tighten the handbrake with their own hands. The most common problem is excessive cable tension. In pursuit of the minimum number of clicks, drivers overtighten the nut, which is why the pads constantly touch the drum.
This leads to rapid wear of the linings, overheating of the brake system and increased fuel consumption. In addition, a tightened cable can burst at the most inopportune moment, leaving the car without a parking brake. Always check the wheel for free play after adjustment.
- โ Don't ignore pad wear and rely only on adjustments
- โ Do not use WD-40 on brake friction surfaces.
- โ Do not leave the brake mechanism without protective caps
Another mistake is the lack of checking the condition of the cables. If the cables have traces of corrosion or a frayed sheath, adjustment does not make sense. In such cases, the cables break suddenly, often while moving or during an emergency stop.
Don't forget to also check the condition of the return springs. Weak springs cannot return the pads to their original position, which leads to their constant friction against the drum. If the springs are stretched, they need to be replaced, even if they are visually intact.
FAQ: Answers to popular questions
How much does it cost to replace the handbrake cable on a Skoda Rapid?
The cost of replacing cables in the service usually ranges from 1,500 to 3,000 rubles per pair, depending on the region and the complexity of access. The price of the cables themselves varies from 2000 to 4000 rubles for a set of original spare parts.
Is it possible to tighten the handbrake without removing the drums?
Theoretically, you could try tightening the cable through the adjusting nut under the tunnel, but this is less effective. Without removing the drums, it is impossible to check the wear of the pads and the condition of the eccentric, which can lead to hidden problems.
Why doesn't the handbrake hold after adjustment?
Most likely, the pads are worn to the limit or the eccentric mechanism is jammed. It is also possible that the cables have stretched so much that the adjusting nut is unscrewed all the way. In this case, parts need to be replaced.
How often should you check the condition of the handbrake?
It is recommended to check the travel of the handbrake lever every 10,000 km or at each scheduled maintenance. If the number of clicks increases, adjust or diagnose the mechanism.
Do I need to change the cables in pairs?
Yes, it is highly recommended that you replace your parking brake cables in pairs. This will ensure even tension and equal force on both wheels, which is critical for the vehicle's stability.
