Brake balance query
Discussion
Noticed when I was cleaning the beast yesterday (prior to taking it out for a thrashing 
) that the rear wheels had significantly more brake dust than the front.
This raises a couple of questions:
Is this likely to be because the brakes are biased towards the rear? And if so, should they be?

It would be highly dangerous to have the brakes biased to the rear.
Suggestions are:
Handbrake not fully released.
Dust release can be greater if discs are "rougher" at rear than at front.
Pad material may differ front to rear, hence more dust may be released by pad material used on rear.
Brake Dust from front may well be "blow" rearwards and "appear" that rears have more dust !!
Finally, your front brakes are not working.....;-))

It is common to have different pad compounds front and rear, and different compounds can cause different amounts of dust. However, my experience has been that the front wheels invariably collect more dust than the rears. It would be worth checking the rear wheel temperatures just to make sure the rear brakes aren't dragging. This could be caused by sticking sliders or the handbrake mechanism.
The correct brake balance has most of the braking at the front (roughly twice as much as the back under heavy braking) so your brake balance would have to be massively far out to end up with the rears doing more work than the fronts. Unlikely unless you have a major brake failure, but this would also make the car swap ends every time you looked at the brakes which you would probably have noticed!

Braking behaviour is perfectly normal so I don't think it is a balance issue. Perhaps it is the pad compound. Gassing Station | Chimaera | Top of Page | What's New | My Stuff
