The soft pedal or brake pedal of the increase may be due to heavy wear on brake pads, brake fluid leakage, the presence of air in the hydraulic drive system.
To correct these faults need to replace brake pads, brake fluid flow to remove and replace damaged parts and to remove air – pump drive system.
Pad change when the braking plate is erased to a thickness of 1 mm. To measure the thickness of the pads do not need to climb into the saddle with a ruler. As a rule, there are a few lining or a groove that just do not get to 1 mm to the metal base. Noticing that the grooves of these little that is left is to replace the pads immediately. Changing pads and brake discs especially, control to the brake fluid does not leak from the tank.
To remove air from the hydraulic brakes need pumping. Air significantly reduces the effectiveness of the braking system. The air can get into the hydraulics because of depressurization of the system by replacing individual components or the repair, as well as when replacing the brake fluid.
If the car is beginning to divert toward the braking, the possible failure of the wheel brake cylinder, excessive lubrication or wear pads brake pads brake wheel.
To eliminate these troubles, you need to replace brake pads and faulty cylinder. Contaminated shoes should be washed.
If you hear noise when you press the brake pedal or vibrations occur, the cause of this is pollution brakes, breakdown or weakening of the tightening spring rear brake pads, linings excessive wear of brake pads, uneven wear of brake discs or drums.
To correct these faults should be washed with contaminated stocks, and damaged or worn parts replaced with new ones.
