Hey lads,
Does anybody know what a floating brake disc is :dunno: and what its advantage or disadvantages are? :ponder:
And will brake capilers off a type RA IMPREZA be a direct fit for my B4? :thumbsup: Thanks
 
I know that they have a system called floating disc breaks on downhill mountain bikes. It's kind of a system where the caliper is not directly connected to the swing arm.

Not sure how you'd do it with a car.
 
Found this on Brembo site...

There are several reasons that a two-piece floating disc assembly is of benefit. First, by using an aluminum bell for the hub section of the disc saves a great deal of weight. Since this is both rotating and unsprung, it benefits the acceleration, braking, and handling of the vehicle. Secondly, it is better able to handle the large temperature changes that a brake disc experiences. During severe use, temperature variances become present in a one-piece disc and generally cause warping of the disc. This not only results in vibration of the vehicle, and pulsing of the brake pedal, but also pushes the pistons farther away from the disc. In a two-piece floating disc assembly, the iron disc heats up more uniformly, and the controlled float which is present allows for the differential expansion of the very hot brake disc, and the relatively cool aluminum bell. This allows the disc to be used under severe conditions without having a detrimental effect.

Don't know bout RA brakes on B4... Sorry fella!

:thumbsup:
 
well that clears that up anyway sound :thumbsup:
Have to find out about the b4 and type r brakes, just bought some!!! :shock:
 
Regarding brake calipers, Straight bolt on job as far as I know!
Search for 4 pots on a b4, in the search bar!
I'd just get a straight swap EBC or similar grooved disc!
