Brake Discs and Pads Rear in Vantaa

When rear brake discs need replacing

Rear discs are usually more fragile than other braking components because they are thinner and carry the parking brake. Their biggest enemy is rust — particularly when the car sees little use and short journeys, because the rear discs never heat up and salt and moisture remain on the surface. A rear disc can therefore still be good for wear but ready for replacement because of corrosion. Another common reason for replacement is uneven thickness. If one side's pads seize in the caliper, the other pad drags continuously and the disc wears unevenly. This causes vibration through the rear of the car, especially during motorway braking, felt as a pulse through the brake pedal. Discs are always replaced as an axle pair. This ensures braking force is distributed evenly and the car tracks straight during emergency braking.
