Withdrawal
Remove the wheel trim.
Mark the position of the rims on the front wheel hubs with paint. Thanks to this, the balanced wheel is subsequently set to the same position.
Loosen wheel bolts.
Raise the front of the car and remove the wheel.
Attention: Changing the block from the inside to the outside and vice versa, as well as from the right wheel to the left and vice versa is not allowed. Swapping can cause uneven braking. It is imperative to replace all front wheel brake pads at the same time, even if only one pad has reached its wear limit. When reinstalling the brake pads, they should be marked when removed.
Remove the wear sensor connector from the left brake caliper (arrow), without pulling on the wire.
Loosen the bottom bolt -3- of the piston housing while holding the guide bolt -4- with a wrench.
Press wear indicator -7- out of rear plate with a screwdriver.
Attention: When the pistons are depressed, the brake fluid is squeezed out of the brake cylinders into the expansion tank. Monitor the fluid level in the reservoir. You may need to suck out the liquid.
To aspirate the fluid, you can use a vessel used to bleed air from the brake system, or any plastic bottle that is intended only for brake fluid. Do not use drink bottles! Brake fluid is poisonous and must never be sucked out by mouth through a hose. Use an aspirator. After replacing the pads, the brake fluid level should not exceed the MAX mark, as the fluid expands when the temperature rises. Leaking brake fluid gets on the brake master cylinder, destroys the paint and causes corrosion.
Attention: If the brake pads are heavily worn, check the ease of movement of the piston. In case of heavy movement of the piston, send the caliper for repair (the robot must be performed at the service station).
To prevent disc brake squeaks, apply a racing coat of lubricant (e.g. Plastitube, Tunap VC 582/S, Chevron SRJ/2, Liqui Moly LM-36 or LM-508-ASC) on the back of the brake pads. In this case, the lubricant is applied only to the back side. Under no circumstances should grease come into contact with the working surface of the brake pad or the brake disc. If necessary, wipe off the grease and clean the surface with alcohol.
Install intermediate pads from old brake pads to new ones. Glue gaskets to facilitate installation.
Attach wear indicator -7- to inner brake shoe.
Insert both brake pads into the brake caliper. So that the clamping springs -2- point upwards and are parallel to the top edge of the block. Make sure the shims are properly seated on the rear sides of the brake pads.
Lower the piston housing and secure to the caliper with a new self-locking bolt -3- with a tightening torque of 35 Nm. While doing this, hold the guide bolt -4- with a wrench. Attention: The self-locking fastening bolt can only be installed once.
Connect the wear sensor connector on the left side of the vehicle to the connector on the brake caliper.
Place the wheel in compliance with the marked position of the disk on the hub. Lower vehicle and cross-tighten wheel bolts to 110 Nm.
Caution: With the vehicle stationary, depress the brake pedal several times until a hard resistance appears.
Check the brake fluid level in the expansion tank, top up if necessary to the MAX mark.
Carefully let the new brake pads run in, for which, by lightly pressing the brake pedal, brake the car several times from a speed of 80 km / h to 40 km / h. Allow the brakes to cool down between successive brakings. Attention: But for the first 200 km, avoid sudden braking until the car comes to a complete stop.

Apply a thin layer of lubricant to prevent disc brake squeaks (e.g. Plastitube, Tunap VC 582/S. Chevron SRJ/2, Liqui Moly LM-36 or LM-503-ASC) on the back of the brake pads. In this case, the lubricant is applied only to the back side. Under no circumstances should grease come into contact with the working surface of the brake pad or the brake disc. If necessary, wipe off the grease and clean the surface with alcohol.
