Application. Before deciding that the cause of the malfunction is related to the brake system, make sure that:
- A) Tires are in good condition and properly inflated (Chapter 1),
- b) the front wheel alignment is correct,
- V) the placement of cargo on the vehicle does not lead to an uneven distribution of the load.
39. Pulling the car in any one direction when braking
- 1. Incorrect tire pressure (Chapter 1).
- 2. Incorrect adjustment of the angles of installation of the middle wheels.
- 3. Front or rear tires do not match.
- 4. Reduced capacity of brake lines or hoses (chapter 9).
- 5. Incorrect operation of the caliper (chapter 9).
- 6. Loose suspension elements (chapter 10).
- 7. Loose caliper (chapter 9).
- 8. Increased wear of the brake pad or disc on one side.
40. Noise (screech or screech) when braking
- 1. Worn front and/or rear disc brake pads. The noise is due to the wear sensor rubbing against the disc. Replace pads with new ones immediately (chapter 9).
41. Irregularity or vibration (pedal pulsation) when brakes are applied
42. To stop the car, an increased force on the brake pedal is required
- 1. Improper operation of the vacuum brake booster (chapter 9).
- 2. Partial system failure (chapter 9).
- 3. Increased pad wear (chapter 9).
- 4. Brake caliper piston sticking (chapter 9).
- 5. Contamination of brake pads with oil, grease or brake fluid (chapter 9).
- 6. Installed new brake pads, which have not yet run in. The new material will take some time to burn in to the disc.
43. Increased brake pedal travel
- 1. Partial malfunction of the brake system (chapter 9).
- 2. Lack of brake fluid in the master cylinder (chapter 1 and 9).
- 3. Presence of air in the system (chapter 1 and 9).
44. Sticky brakes
- 1. Incorrect adjustment of the brake light switch (chapter 9).
- 2. Master cylinder pistons do not return properly (chapter 9).
- 3. Reduced capacity of brake lines or hoses (chapter 1 and 9).
- 4. Incorrect parking brake adjustment (chapter 9).
45. Locking or uneven braking
- 1. Incorrect operation of the pressure regulator (chapter 9).
- 2. Incorrect operation of the vacuum brake booster (chapter 9).
- 3. Jamming of the brake pedal mechanism (chapter 9).
46. Brake pedal feel «soft» when you press
- 1. Presence of air in hydraulic lines (chapter 9).
- 2. Loosening the master cylinder bolts (chapter 9).
- 3. Malfunction of the main cylinder (chapter 9).
47. The brake pedal moves to the floor with little resistance
- 1. Lack or complete absence of brake fluid in the hydraulic brake reservoir due to leakage through the piston (neither) caliper (chapter 9).
- 2. Loose, damaged or disconnected brake lines (chapter 9).
- 3. Malfunction of the master cylinder (chapter 9).
