Braking Diagnostics

We can diagnose your braking problems too. Quite often brakes are misdiagnosed, i.e. wheel vibration. This is normally caused by a wheel balance issue, but if this has been eliminated, then there is a possibly that a brake calliper is sticking on; as the heat increases the brake disc will deform out of shape (warp) and cause vibration through to the cabin and it’s input devises (the pedals and steering wheel etc). Brake disc wear and warping are a major issue since asbestos brake pads were abolished. The replacement material is much harsher to the disc. Although the materials are improving the discs still get a much harder life. On average a brake disc will need replacing every second set of brake pads. If your brake discs have not worn too much but are causing a vibration then we can skim the discs (while on the car) with a Brake Lathe. This impressive piece of kit machines both sides of the brake discs at the same time; thus making them true to the hub. The result: all vibrations are eliminated and brake-pedal feel is restored.

Often overlooked is the brake fluid. It sits unassumingly in its little reservoir under the bonnet doing, the often un-thanked, arduous task of transferring pressure from the brake pedal down to the brakes; allowing the brake pads and discs do their job, at this end the fluid is subject to some very high temperatures. The fluid itself is hydroscopic, which means it absorbs moisture from the air. Unfortunately this means that the “wetter” the fluid gets the less capable it is of doing its job properly. On this note the brake fluid should be changed annually on all M Power cars and bi-annually on all other cars.
