Check the brake system
| 1. The reason for reducing the braking performance may be unsatisfactory work of the vacuum amplifier. To express his check, click a few times on the brake pedal with the engine off, to remove the vacuum amplifier, then hold the pedal, start up the engine. If the engine start pedal slightly dropped and there is no vibration in the pedal booster is in good. |
NOTE If your car is equipped with anti-lock brakes (ABS), when you press the brake pedal may be a slight vibration - in this case it is not a malfunction. |
2. If the pedal remains fixed, check the integrity and reliability of fastening of a hose connecting the vacuum booster to the intake manifold of the engine (the receiver) and the body of the vacuum amplifier (see. "Testing the brake servo"). Defective hose Replace or repair. If the hose is in good condition, requires replacement of the vacuum amplifier (see. "Replacement of the vacuum amplifier"). |
3. If braking is accompanied by the beats and pulsating brake pedal, you should first check the status of the front disc brake. |
4. With the vehicle on the jack, remove the front wheel and check the brake disc. The thickness of the brake disc should be at least 17 mm. The disc surface must be flat and smooth on both sides. If the surface of the disc in places covered with rust, which usually happens after a long parking lot with unseasoned brakes, try to clean work surface with fine emery cloth. If this procedure does not work, it will have to pay in grinding wheels or replaced. |
| 5. Check the mobility of the brake piston. To do this, two screwdrivers try to budge the brake caliper. If the caliper can not move, then it stuck piston in the brake cylinder. |
A WARNING Wedging the piston cylinder leads to a constant braking of the appropriate wheels when the pedal is released and the vehicle skidding while braking. |
The parking brake actuates the rear brakes cable connecting the parking brake lever and control gear brake pads. Many drivers try as little as possible to use the parking brake in order to prolong his life, and achieve the opposite result. If you do not use the parking brake in a cable cover stagnate dirt and moisture accumulates rust rope ceases to move and breaks. So use the parking brake when you need it, but do not forget from time to time adjust its drive (see. "Adjusting parking brake").
