Note: Before deciding whether there is a problem with the brake system, make sure that the tires are not worn out and that their pressure is correct (see chapter 1), as well as in accordance with the norm of geometric parameters of wheel installation and uniform loading of the vehicle.
45 The car pulls to the side when braking
1. Oily or damaged brake pad linings on one side of the car. Carry out inspection as described in Chapter 9.
2. Excessive wear on the brake pads on one side. Inspect and replace as necessary.
3. Loosening or detaching an element of the front suspension. Check fasteners for tightness (see chapter 10).
4. Caliper malfunction. Remove the caliper and check for a stuck piston or other problem.
46 The brakes squeal when you press the pedal
1. Excessive wear on the brake pads. A squealing noise is produced by the lining wear indicator when rubbing against the disc (not on all models). Replace the pads immediately (chapter 9). If the linings are completely worn out, you should inspect the disc for possible damage, as described in Chapter 9.
2. Oily or dirty brake pad linings. Make a replacement.
3. Mismatched brake pad type. Replace the pads in accordance with the technical requirements.
47 Excessive brake pedal travel noted
1. Malfunction of one of the system elements. Inspect the entire system (chapter 9) and fix the problem.
2. Lack of brake fluid in the master cylinder reservoir. Check (Chapter 1) and if necessary, add fluid and bleed the system.
48 When pressed, the pedal fails
1. Air penetration into the hydraulic system. Pump up (chapter 9).
2. Failure of the brake hose. Inspect the system hoses and tubes. Replace if necessary.
3. Loosening of the main brake cylinder.
4. Failure of the master brake cylinder (chapter 9).
49 To stop the car, you need to apply increased force to the pedal
1. Malfunction of the vacuum brake booster (check is described in Chapter 1, recovery - in Chapter 9).
2. Excessive wear on the pad linings. Inspect and replace if necessary (chapter 9).
3. One or more caliper pistons are stuck. Inspect and replace if necessary (chapter 9).
4. Oily or dirty brake pad linings. Inspect and replace the pads as necessary (chapter 9).
5. New brake pads that have not been broken in. Over time, the linings will rub against the discs.
50 The pedal does not feel elastic
1. Low level or lack of brake fluid in the master cylinder reservoir caused by a leak through the piston seal (to her) caliper, as well as loose connections or damage to the brake hoses. Inspect the entire system and troubleshoot any problems.
2. Leaking master cylinder seals (chapter 9).
51 When you press the brake pedal you feel a pulsation
Disk failure. Remove disk (chapter 9) and check its runout and the degree of deviation from the norm of geometric parameters. Machining or replacing discs (in pairs on any of the axes).
