The braking system is a critical safety element of any vehicle, and Skoda Rapid in this regard is no exception. The rear brake mechanisms in this model are often made in the form of drum devices, which creates certain differences in the maintenance process compared to disc counterparts. Many owners are faced with the need to replace them themselves in order to save money or control the quality of spare parts.
The process of removing and installing new elements requires attention to detail, especially when working with tension springs and the pad supply mechanism. Failure to do so may result in the wheel being unable to be reinstalled or new parts wearing unevenly. In this article we will analyze all the stages of work so that you can confidently carry out the repair yourself.
Preparation of the workplace and necessary tools
Before starting any manipulations with the vehicle's chassis, it is necessary to ensure that the vehicle is securely secured. The car must be parked on a level surface, and wheel chocks must be installed under the front wheels. Failure to do so may result in the machine rolling and causing serious injury.
For a successful replacement, you will need a standard set of wrenches, including 13 and 15 sockets, as well as a special tool for compressing the brake caliper piston if we are talking about the disc version of the rear brakes. For a drum system, you will need a circlip puller and a soft-faced hammer to remove the drum carefully.
- ๐ง Socket set and ratchet (sizes 13, 15, 17 mm)
- ๐จ Hammer and spatula for removing jammed parts
- ๐ข Wheel wrench and jack with reliable supports
- ๐งด Brake cleaner and lithium slide grease
It is also important to prepare a container for draining brake fluid if the process requires bleeding the system. Work in a well-ventilated area, as brake fluid vapors and dust from old pads are harmful to health.
โ ๏ธ Attention: Never press the brake pedal with the wheel and pads removed - the piston may completely come out of the cylinder, which will lead to fluid leakage and difficulties during assembly.
Removing the wheel and brake drum
Once the vehicle is securely secured, raise the rear axle using a jack. Remove the wheel rim by unscrewing the mounting bolts. Now you need to access the brake mechanism. If your vehicle has drum brakes, you will need to remove the drum itself, which is attached to the hub.
In some cases, the drum may be stuck to the hub due to corrosion or wear. In such a situation, you should not hit it with a hammer with all your might, as you can damage the wheel bearing. It is better to use special pullers or carefully tap the edges of the drum through a wooden spacer.
- ๐ Unscrew the wheel mounting bolts and remove it
- ๐ฉ Loosen or unscrew the drum guide pins (if equipped)
- ๐จ Carefully remove the drum, tapping it if necessary
- ๐งน Clean the surface of the hub from dirt and rust
If the drum cannot be removed by hand, check whether the handbrake is stuck. Sometimes the shoe supply mechanism requires adjustment so that the drum can freely come off the studs. In this case, access may be required through access holes in the rear wall of the drum.

Diagnostics and removal of old pads
After removing the drum, you will see the internal structure of the brake mechanism. There are two pads, an expansion fork and a spring system. First of all, pay attention to the wear sensor, if it is included in the design of your equipment. On Skoda Rapid rear pads often do not have an electrical sensor, but you can visually assess their condition without any problems.
First, remove the upper and lower springs that tighten the pads. Use special brake spring pliers to avoid damaging the protective coating or injuring your hands. Be prepared for the fact that the springs may be very worn and require replacement along with the pads.
Then disconnect the handbrake lever from the shoe. To do this, you need to press the lock washer and remove the rod. Pay attention to the condition of the handbrake cable end - if it is stuck or has signs of corrosion, this can lead to uneven wear on the new pads.

- ๐ง Disconnect the parking brake cable from the shoe lever
- ๐ Check the condition of the expansion fork and support pins
- ๐ Measure the thickness of the friction lining of the old pads
If you plan to replace not only the pads, but also the drum, pay attention to its internal diameter. If it exceeds the permissible limit specified in the technical documentation, replacement of the drum is mandatory, otherwise the new pads will not provide proper braking.

Features of working with the supply mechanism
An important element of the system is a mechanism for automatically adjusting the gap between the pads and the drum. It is a screw pair that moves the pads apart when worn. When installing new, thicker pads, this mechanism must be shortened so that the drum can slide into place.
To do this, use a screwdriver or a special wrench to turn the adjusting screw until the distance between the pads is minimal. This must be done carefully so as not to break the thread. If the mechanism is rusty and does not turn, it will have to be replaced entirely, since attempts to turn it by force can lead to breakage.
In some cases, especially on high mileage vehicles, the mechanism may become blocked by dirt and corrosion. In such a situation, it is recommended to pre-treat it with a penetrating lubricant and give it time to work before attempting adjustment.
โ ๏ธ Caution: If the feed mechanism is not adjusted before installing the drum, you risk damaging the threads or stripping the nut when attempting to install the drum, resulting in costly repairs.
What to do if the supply mechanism does not work?
If the adjusting screw does not turn, try gently tapping it with a hammer through a wooden spacer. Sometimes heating the joint with a hair dryer helps, but be careful with plastic parts nearby. In extreme cases, the mechanism will have to be cut out with a grinder and replaced with a new one, which will require careful installation.
Installing new pads and assembling the mechanism
Installing new pads begins with securing the handbrake lever. Make sure the lock washer is snug and free of play. Then put the pads on the support pins and install the expansion fork between them. It is important that the fork takes the correct position in the groove of the feed mechanism.
Next, install the upper and lower springs. At this point, use long-handled tongs for better leverage. The tension of the springs must be uniform so that the pads do not warp. After installing the springs, check whether the pads move freely on their supports.
- ๐ฉ Attach the handbrake lever to the shoe
- ๐ง Install the expansion fork and spread the pads
- ๐ Tension the upper and lower springs
- ๐ Check the free play of the pads and the absence of distortions
Before installing the drum, double check that it is assembled correctly. Make sure all springs are in place and the handbrake mechanism operates smoothly. Clean the surface of the drum from dust and dirt so that the new pads fit evenly.
Checking and adjusting the hand brake
After installing all the elements and putting on the drum, you need to check the operation of the hand brake. Tighten the lever inside and make sure the wheels lock. Then release the lever - the wheels should rotate freely without touching the pads.
If the handbrake does not hold or, on the contrary, the wheels jam, adjustment will be required. It is carried out through an adjusting nut located under the trunk floor or under the bottom of the car, depending on the modification. Skoda Rapid. The adjustment is made until the lever has the required number of clicks (usually 3-5).
Also, do not forget to check the condition of the handbrake cables. If they show signs of wear or corrosion, it is best to replace them immediately to avoid problems in the future. The cables must move freely in the sheaths without jamming.
Final assembly and testing
Install the wheel rim back onto the hub and tighten the mounting bolts to the recommended torque. Lower the vehicle to the ground and tighten the bolts again with a torque wrench. Now you can move on to testing the brake system.
Before starting to drive, press the brake pedal several times so that the pads take their working position. This is especially important after replacing the rear drum shoes, as the drive mechanism may take time to adapt. Test the brakes at low speed in a safe location.
During operation, pay attention to the behavior of the car when braking. If the machine pulls to one side or you hear strange noises, the installation may have been performed incorrectly. In this case, it is recommended to repeat the check of all nodes.
Correct adjustment of the drive mechanism and handbrake is the key to ensuring that the new pads will last a long time and will not overheat due to constant braking.
Comparison of brake systems and selection of spare parts
Owners Skoda Rapid are often faced with the question of choosing between original spare parts and analogues. Original pads provide guaranteed quality and compatibility, but are significantly more expensive. Analog products may offer better value for money, but require careful selection.
When choosing pads, pay attention to the composition of the friction mixture. For city driving, soft compounds are suitable, which generate less dust but can wear out faster. For an aggressive driving style, it is better to choose harder compounds that are resistant to overheating.
| Brand | Type | Approximate price | Features |
|---|---|---|---|
| Skoda Original | Original | High | Perfect compatibility, long service life |
| TRW | Premium analogue | Average | Excellent quality, often factory installed |
| Textar | Premium analogue | Average | Stable performance, low noise |
| Finwhale | Budget analogue | Low | Affordable price, but wear out faster |
Choose trusted manufacturers to avoid environmental and safety problems.
It is also worth noting that on some versions Skoda Rapid rear brakes can be disc. In this case, the replacement process is different: you need to unscrew the caliper, compress the piston and replace the pads. The principles for selecting spare parts remain the same.
โ ๏ธ Attention: Never mix pads from different manufacturers on the same axle. This can lead to uneven braking and loss of vehicle control.
Frequently asked questions and answers
Do I need to change the drum along with the pads?
Not always. If the drum wear is within acceptable limits and there are no deep grooves on it, it can be reused. However, for better braking performance and longevity of the new pads, it is recommended to replace the drum, especially if it shows significant signs of wear.
How can you tell if the rear pads are worn out?
Wear is indicated by a squeaking or grinding noise when braking, a decrease in the effectiveness of the brake system, as well as a visual inspection through the technological holes of the drum. On disc brakes, the wear indicator light may come on.
Is it possible to replace just one pair of rear pads?
Absolutely not. Brake pads are always replaced in pairs on one axle (both rear wheels). Replacing only one side will result in uneven braking and the vehicle pulling to the side.
What to do if the drum cannot be removed?
Try unscrewing the guide pins, if there are any. If the drum is stuck, use a penetrating lubricant, gently tap it with a hammer through a wooden spacer, or use a puller. Never use excessive force to avoid damaging the hub.
Following all recommendations and using high-quality tools will allow you to successfully replace the rear pads with Skoda Rapid with your own hands. Not only will this save you money, but it will also give you peace of mind that your car's braking system is working properly.
