Too much brake pedal play
Partial or complete wear of the brake linings
- Replace brake pads
Failure of one of the brake circuits
- Check brake circuits for brake fluid leakage
The brake pedal is pressed far down and springy
Air in the brake system
- Bleed air from the brake actuator
Too little brake fluid in expansion tank
- Add brake fluid, bleed the brakes
Steam bubble formation
- Most often after a heavy load on the brakes, for example, on a steep descent
The braking effect is reduced, the brake pedal is depressed to the stop
Leaky pipeline
- Tighten the nuts at the joints or replace the pipeline
Damaged cuff on the brake master cylinder or on the wheel cylinder
- Update cuff. In the master brake cylinder, replace the internal parts, if necessary, replace the master cylinder
Poor braking action despite a lot of effort applied to the brake pedal
Oily brake pads
- Update your pads
Wrong or hardened brake lining
- Update the linings, apply only original car manufacturer's linings
Faulty vacuum brake booster, defect and porosity of the booster hose
- Check booster and booster hose
Worn brake pads
- Replace pads
The brake mechanisms of the wheels do not act simultaneously (brakes «pull» one way)
Tire pressure not correct
- Check the tire pressure and bring it up to normal
Uneven tire wear
- Replace worn tires
Oily brake pads
- Update your pads
Brake linings of different brands are installed on the same bridge
- Replace pads, use only original pads from the vehicle manufacturer
Poor condition of the working surface of the brake lining
- Replace pads
Contaminated caliper cavities
- Clean the seating and guiding surfaces of the caliper brake pads
Wheel cylinder corrosion
- Replace brake caliper
Uneven brake lining wear
- Update your brake pads (both wheels) and check the stroke of the caliper
Brakes work on their own
Equalizing hole in brake master cylinder clogged
- Clean the cylinder and replace its internal parts in the workshop
The gap between the pusher and the piston of the main brake cylinder is too small
- Check clearance
Heating up the brakes while driving
Equalizing hole in brake master cylinder clogged
- Clean the brake master cylinder and replace its internal parts in the workshop
Heavy brake travel
- Lubricate the moving parts of the drum brake. Move the caliper (In workshop)
Rattling brakes
Wrong brake pads
- Replace pads. Use only original car manufacturer's pads
The brake disc is covered in places with corrosion
- Thoroughly clean your drive
Brake disc has lateral runout
- Modify disk or replace
Brake pads do not move away from the brake disc
Wheel cylinder corrosion
- Overhaul the caliper, replace if necessary
Uneven pad wear
Wrong brake pads
- Replace pads. Use only original car manufacturer's pads
Caliper dirty
- Clean the cavity of the caliper
Difficult stroke of wheel cylinder pistons
- Design Pistons
Leakage of the brake system
- Check the tightness of the brake system
Wedge-shaped brake pad wear
Brake disc does not rotate parallel to caliper
- Check the contact surface of the caliper
Caliper corrosion
- Eliminate corrosion and contamination of calipers
Squealing in the brakes
Often attributed to atmospheric influences (humidity)
- No intervention is required if the brake squeak occurs after a long stop in high humidity, but after the first braking it no longer occurs
Wrong brake pads
- Replace pads. Use only original car manufacturer's pads
Brake disc does not rotate parallel to caliper
- Check the contact surface of the caliper
Caliper cavities are dirty
- Clean the cavity of the caliper
Pulsating brakes
Action ABS
- Normal, no intervention required
Brake disc lateral runout or disc thickness tolerance too high
- Check runout and disc thickness tolerance. Repair or replace disk
Brake disc does not rotate parallel to caliper
- Check the contact surface of the caliper
ABS warning light on while driving
Low battery power (voltage less than 10 volts)
- Check battery voltage. Make sure the battery charging light goes out after starting the engine. Otherwise, check the condition of the ribbed belt and alternator
- Review recommendations for vehicle active safety systems Check wire terminal «masses» (-) from the return pump of the hydraulic unit and check that it is firmly fixed and not rusted
ABS malfunction
- Contact a workshop to check the ABS
