Proper operation of the braking system is fundamental to the safety of any vehicle, and Škoda Rapid is no exception. Many owners of this model are faced with a design feature of the rear axle, where classic drum mechanisms are installed rather than disk ones. This solution, typical of many budget and mid-size cars, has its advantages in the form of durability and protection from dirt, but requires specific knowledge when servicing.
Replacing rear brake pads Škoda Rapid often raises questions among beginners, since the mechanism is hidden inside the drum and has a spring drive. Incorrect assembly can lead to wheel jamming or, conversely, lack of braking. In this article we will analyze in detail the process of dismantling and installing new elements, paying special attention to the intricacies of working with the handbrake mechanism.
Design features of the Rapid drum unit
Rear suspension model Škoda Rapid designed using a "torsion beam" type beam, at the ends of which drum brakes are mounted. Unlike disk systems, here the working surfaces are located inside a rotating drum, which creates specific conditions for heat removal.
It is important to understand that this system uses a self-feeding mechanism that automatically compensates for friction lining wear. If this mechanism does not work, you will have to press the brake pedal too hard. Also note that the rear brakes are Rapid often serve as a parking brake, which adds complexity to replacement.
- 🔧 The drum mechanism is protected from dust and water better than its disk counterpart.
- 🛑 The parking brake is operated via a separate lever inside the drum.
- 📏 The gap is adjusted automatically when driving in reverse.
The handbrake mechanism has a cable drive, which can become sour or stretch over time. When replacing pads, be sure to check the free movement of the cable and its mobility in the sheath. If the cable does not return to its original position, the new set of pads will quickly wear out or jam.
Preparing tools and selecting consumables
For a quality replacement, you will need a standard set of mechanic tools, but there are nuances specific to drum brakes. You will definitely need a spring puller that allows you to safely remove powerful springs without the risk of injury to your fingers.
The quality of spare parts plays a decisive role. For Škoda Rapid suitable original components from VAG, as well as proven analogues from brands like TRW, Brembo or Ate. Cheap Chinese analogues often have inappropriate sizes or friction linings that begin to creak immediately after installation.
- 🔨 Brake spring puller (required for safe disassembly).
- 🧼 Brake system cleaner (spray) and wire brush.
- 🛢️ Special lubricant for calipers and guides (do not use graphite!).
Before starting work, be sure to prepare the site. The drums are attached to screws, which often stick. Use penetrating lubricant beforehand. If the screw is stripped, you may have to use a bolt cutter or drill it out, which will make the job much more difficult.

Step-by-step instructions for dismantling and replacement
The first step is to secure the car on a flat surface and place chocks under the front wheels. Remove the wheel, unscrew the hub protective cap (if equipped), and then loosen the brake drum bolts. Please note that some models may have screws securing the drum itself to the hub on the reverse side.
It is important to act carefully as the drum may become stuck to the hub due to corrosion. If it does not come off by hand, try lightly tapping the inside of the drum in a circle with a rubber mallet. Never hit the brake disc or hub directly to avoid damaging the bearing.
☑️ Preparing to remove the drum
After removing the drum you will see the internal structure. Before disassembling the mechanism, photograph the location of the springs and levers. This will save you a lot of time when reassembling. Using a puller, remove the lower tension spring, then the upper one.
Remove the support pins holding the pads. Carefully remove the pads, being careful not to damage the handbrake cable. Pay attention to the condition of the support pin boots - if they are torn, they need to be replaced.
Cleaning and diagnostics of mechanisms
Before installing new parts, all parts must be thoroughly cleaned. Use brake cleaner and a brush to remove accumulated brake dust. This dust is very harmful to the lungs, so wear a mask and preferably outside or in a well-ventilated area.
Check the condition of the brake drum. Measure its inner diameter with a caliper. If it exceeds the permissible maximum specified in the service book, the drum must be replaced or re-grooved. The maximum permissible diameter for the Škoda Rapid drum is 200.8 mm.
- 🔍 Inspect work surfaces for deep grooves and burrs.
- 🌡️ Check for cracks on the drum body (especially in the area of the cooling fins).
- 🔄 Assess the wear of the hub bearing - it should not play.
Don't forget to lubricate the support pads where the pads rest. Use high temperature brake lubricant. Apply a thin layer only to metal-to-metal contact areas, avoiding contact with friction linings.
Why can't I use regular lithium grease?
Conventional lubricant can liquefy at high temperatures and get onto the pads, resulting in reduced braking performance and the appearance of a characteristic burning smell.
Installing new pads and adjusting
Installing new pads begins by attaching the handbrake lever to the rear pad. Make sure the retaining ring is securely seated. Then put the pads on the support pins and connect them with tension springs.
Assembling the handbrake mechanism requires attention. The cable must move freely in the lever and not be distorted. Install the upper and lower springs using a special puller. If the spring comes off, it could cause injury, so hold it securely.
Before installing the drum, spread the shoes slightly to check that they rotate freely inside the drum. If there is any snagging, adjust the sliding mechanism.
After installing the drum and wheel, the gap must be adjusted. To do this, sharply press the brake pedal several times, then lift the car and spin the wheel in reverse. This activates the self-feeding mechanism.
Common mistakes and how to avoid them
One of the most common mistakes is incorrect installation of springs. If you mix them up or don't lock them completely, the pads will wobble and make a loud knocking noise when you drive. Always refer to the photo taken before disassembly.
Another problem is grease getting on the friction linings. If this happens, the pads must be replaced immediately, since it is impossible to wash them to factory specifications. Brake dust and dirt can also cause squeaking, so cleaning is a must.
⚠️ Caution: Never attempt to adjust the handbrake by simply tightening the nut on the cable without checking the clearances. This may cause the brakes to overheat while driving!
It is also worth checking the condition of the working cylinder boot. If it is torn and brake fluid leaks from inside, the cylinder must be replaced or repaired. Working with the liquid requires caution, as it is aggressive to the paintwork.

Proper replacement of rear pads guarantees safe operation of the vehicle in any conditions. Do not skimp on the quality of spare parts and do not skip the diagnostic stage. Regular maintenance of the brake system will extend the life not only of the pads themselves, but also of other suspension components.
Timely replacement of pads and cleaning of the mechanism prevents costly repairs to the drum and hub in the future.
Frequently asked questions (FAQ)
How can you tell if your rear drum pads are worn out?
Unlike disc pads, drum pads do not have a wear sensor. Wear can be detected by increased brake pedal travel, decreased braking performance, or a squeaking sound when the pedal is pressed. You can also visually assess the thickness of the lining through the technological holes in the drum, if any.
Is it possible to replace the pads without removing the drum?
No, for a complete replacement and diagnostics, the drum pads must be removed along with the drum. Without dismantling it is impossible to check the condition of the hand brake mechanism, support pins and the drum itself.
Do I need to adjust the handbrake after replacing it?
In most cases, the self-feeding mechanism itself adjusts the gap. However, if the handbrake does not hold or is too tight, the cable tension under the vehicle may need to be adjusted.
Why doesn't the drum come off after unscrewing the screws?
Most often this is due to corrosion, due to which the drum has become stuck to the hub. Use penetrating lubricant and a rubber mallet. If that doesn't help, try warming the drum with a hair dryer (with caution).
What lubricants should not be used during maintenance?
It is strictly forbidden to use graphite lubricants, lithol or grease on brake system parts. They can cause jamming of mechanisms or destruction of rubber seals. Use only specialized high temperature brake lubricants.
