Brake Disc Skimming
So why resurface discs?
As the diagrams above show, skimming your discs or changing your discs before fitting new brake pads is very important. The old disc fitted with new pads has much less contact area and will generate extra heat.
With our on-car brake lathe, brake discs are skimmed quickly, efficiently and with amazing accuracy. It saves our customer’s money but additionally gets more life from the brake discs that would otherwise have to be disposed of.
Brake discs should be resurfaced when:
- Brake pads are changed but new discs are not necessary, this is likely in at least 50% of all cases. You will not have to bed in the brakes, they will be perfect when you leave.
- There is evidence of brake vibrations due to disc thickness variation or excessive run-out. The only permanent solution to this problem is using the on-car lathe
- Discs are corroded, this causes poor braking performance or imbalence.
- Brakes are noisy. This normally occurs when pads are fitted to ‘lipped discs’ causing brake squeal. This can be correctly by skimming the discs to remove lips and give perfecty flat disc surfaces.
When the brake discs reach their minimum thickness you will then have to change your discs, but bear in mind most discs can be re-skimmed a number of times.
