brake discs & pads replacement in Portsmouth

How do front brake discs work?

The brake disc is a metal plate mounted on the wheel hub that is clamped between **2 brake pads **when braking is applied; this causes friction and slows the vehicle down.

How often should brake discs need replacing?

As a rough guide, your brake discs should last between 50k and 70k miles, but there are many variables that could affect this, including driver behaviour, the weight you carry and the speed you travel.

The law, vehicle regulations and your MOT

What causes brake discs to stop working correctly?

Brake discs wear out over time from continual use. The friction applied by the brake pads, and the intense heat generated, will eventually deform the disc, causing it to become thinner and less effective when performing its job.

Extended use can also cause brake discs to crack, rendering them ineffective. Scars and rust on the disc can be caused by debris thrown from the road and poor weather conditions; this is also effective in reducing the operation of your brake discs.
