Too much free play in the brake pedal
Partial or complete wear of brake linings
Replace the brake pads.
Failure of one of the brake circuits
Check the brake lines for brake fluid leaks.
The brake pedal is pressed far down and springs back
Air in the brake system
Remove air from the brake system.
Too little brake fluid in the expansion tank
Add brake fluid, bleed the brakes.
The braking effect is reduced, the brake pedal is pressed all the way down
Leaky pipeline
Tighten the nuts at the connections or replace the pipeline.
Damaged seal on the master cylinder or wheel cylinder
Update the cuff. In the master cylinder, replace the internal parts, replace the master cylinder if necessary.
Poor braking action despite high force applied to the brake pedal
Oily brake linings
Update your overlays.
Incorrect or hardened brake lining
Update your trims, use only the original trims from the vehicle manufacturer.
The brake booster is faulty, the booster hose is defective and porous
Check the booster and booster hose.
The brake linings are worn out
Replace the pads.
The wheel brakes do not operate simultaneously (the brakes "pull" in one direction)
The tire pressure is not as prescribed
Check the tire pressure and adjust it to normal.
Uneven tire wear
Replace worn tires.
Oily brake linings
Update your overlays.
Brake linings of different brands are installed on one bridge
Replace the pads, use only the original pads from the vehicle manufacturer.
Poor condition of the brake lining working surface
Replace the pads.
Contaminated caliper cavities
Clean the seating and guide surfaces of the brake pads of the caliper.
Corrosion of wheel cylinders
Replace the brake caliper.
Uneven wear of the brake lining
Update your brake pads (both wheels) and check the caliper stroke.
The brakes work on their own
The equalizing hole in the master cylinder is clogged
Clean the cylinder and replace its internal parts in a workshop.
The clearance between the pushrod and the master cylinder piston is too small
Check the gap.
Brakes heating up while driving
The equalizing hole in the master cylinder is clogged
Clean the master cylinder and have its internal parts replaced at a workshop.
Heavy brake action
Lubricate the moving parts of the drum brake. Reassemble the caliper (in the workshop).
Brake rattling
Incorrect brake pads
Replace the pads. Use only the vehicle manufacturer's original pads.
The brake disc is covered with corrosion in places
Clean the disc thoroughly.
The brake disc has lateral runout
Modify the disk or replace it.
The brake pads do not move away from the brake disc

Corrosion of wheel cylinders
Overhaul the caliper and replace if necessary.
Uneven wear of the linings
For disc brakes only
Incorrect brake pads
Replace the pads. Use only the vehicle manufacturer's original pads.
The caliper is dirty
Clean the caliper cavities.
Heavy stroke of wheel cylinder pistons
Spread the pistons.
Brake system leakage
Check the brake system for leaks.
Wedge-shaped wear of brake linings
The brake disc does not rotate parallel to the caliper
Check the caliper mating surface.
Caliper corrosion
Eliminate corrosion and contamination of the calipers.
Squealing brakes
Often attributed to atmospheric influences (humidity)
No intervention is required if the brakes squeal after a long period of parking in high humidity, but do not recur after the first few braking attempts.
Incorrect brake pads
Replace the pads. Use only the vehicle manufacturer's original pads.
The brake disc does not rotate parallel to the caliper
Check the caliper mating surface.
The caliper cavities are dirty
Clean the caliper cavities.
Brake pulsation
ABS action
This is a normal phenomenon and does not require intervention.
For disc brakes only
Lateral runout of the brake disc or excessive disc thickness tolerance
Check the runout and thickness tolerance of the disc. Modify the disk or replace it.
The brake disc does not rotate parallel to the caliper
Check the caliper mating surface.
The ABS warning light comes on while driving
Low battery power (voltage less than 10 volts)
- Check the battery voltage. Make sure the battery charging light goes out after the engine starts. Otherwise, check the condition of the V-belt and the generator.
- Read the recommendations regarding active safety systems in your vehicle
- Check the ground (-) wire terminal from the hydraulic unit return pump and make sure it is securely fastened and not corroded
ABS malfunction
Contact a workshop to have your ABS checked.
