Key brake failure




A warning

Before definition of malfunctions in the brake system, check the front axle, tire condition and tire pressure. If there are faults in the anti-lock brakes system repair should be performed at the service station.


CAUSE
SOLUTION
Increased free stroke of the brake pedal
Worn brake linings Replace the brake pads.
Faulty one of the brake circuits Check the tightness of the hydraulic circuit brake system.
Increased speed and softness of the clutch pedal
The hydraulic brake system, air is present Bleed the hydraulic brake system.
Reduced fluid level in the reservoir popolnitelnom Bring the brake fluid level to normal.
Bleed the hydraulic brake system.
Boiling brake fluid, which typically occurs at a high load on the brake system Replace brake fluid. Bleed the hydraulic brake system.
Low efficiency of the brakes
Leaky hydraulic brakes Identify and eliminate the place negermetichnos minute hydraulic brakes.
Damaged O-ring in the main or working brake cylinder Replace sealing ring.
If damaged O-ring in the brake master cylinder, replace internal parts of the brake master cylinder and the brake cylinder assembly.
When you press the brake pedal is necessary to put more effort
On the brake linings got oil Replace the brake pads.
Mounted brake pads of the appropriate type Replace the brake pads.
Faulty brake servo or leaks in the booster vacuum hose Check the vacuum brake booster vacuum hose and condition, and if neobhodimos minute, replace them.
Worn brake linings Replace the brake pads.
When braking the vehicle leads to the side
Uneven pressure of the tire wheels Check and, if necessary, bring to normal pressure in the tires of the wheels.
Uneven tire wear Replace worn tires
On the brake pads on one side of the car hit oil Replace the brake pads.
On different sides of the vehicle is used brake pads with different friction material Replace the brake pads.
Insufficient contact area of the brake pads with the brake disc Replace the brake pads.
Pollution caliper Clean the surface of the support, interfaced with the brake pads.
Full or partial blockage of the piston in the caliper Replace the caliper.
Uneven wear on brake linings Replace the brake pads and check the smooth running of the piston in the caliper.
Continuous slowdown wheels
Locked compensation hole in the brake master cylinder Clean and, if necessary, replace the internal parts of the brake master cylinder.
Insufficient clearance between the pusher and the piston of the master cylinder Check and, if necessary, adjust the gap between those pusher and the piston of the master cylinder.
Brakes are heated while driving
Locked compensation hole in the brake master cylinder Clean and, if necessary, replace the internal parts of the brake master cylinder.
Insufficient clearance between the pusher and the piston of the master cylinder Check and, if necessary, adjust the gap between those pusher and the piston of the master cylinder.
Brake pads are constantly pressed against the brake disk Check the operation of the brake caliper and, if necessary, replace it.
Strong vibration during braking
Mounted brake pads of the appropriate type Replace the brake pads.
There are traces of the local corrosion on the brake disc Machined working surface of the brake disc.
The deformation of the brake disc Machined or replace the brake disc.
Brake pads are constantly pressed against the brake disc, wherein the wheel is rotated with difficulty
There is corrosion cylinder brake calipers Repair or replace the brake caliper.
Uneven wear on brake linings
Mounted brake pads of the appropriate type Replace the brake pads.
Contamination of the brake caliper Clean the caliper.
Wedging the piston in the caliper Check the condition and, if necessary, replace the caliper.
Leaky hydraulic brakes Locate the leak and repair of the hydraulic brake system.
The wedge-shaped brake linings wear
Caliper is mounted skewed with respect to the brake disc Be sure to install the brake caliper.
There is corrosion in the brake caliper Clean corroded caliper.
The noise of the brakes when braking
Completely worn brake shoe lining Replace the brake pads.
There is a slight layer of rust on the brake discs After several braking noise should abyss and not to appear anymore.
Mounted brake pads of the appropriate type Replace the brake pads.
Caliper is mounted skewed with respect to the brake disc Be sure to install the brake caliper.
Contamination of the brake caliper Clean the brake caliper.
The emergence of strong vibration when braking on the brake pedal or steering wheel
During heavy braking the running anti-lock brakes Repair is not required, as it is normal.
Heavy wear and warping brake discs Check the condition of the brake discs and replace them if necessary.
Loose caliper mounting bolts Check and, if necessary, tighten the caliper mounting bolts.
When driving the ABS warning lamp lights up
System voltage is less than 10 in the car Check the voltage in the vehicle electrical system.
Check that the battery charging indicator lamp goes out after starting the engine.
Otherwise, check the condition of the V-belt and alternator.
Faulty anti-lock brakes Check the condition of the anti-lock braking systems to the service station.
