    Ideally you'd want a floating disc with a fixed caliper like that, otherwise you may start to see the effects of pad knock-back/knock-off after cornering - i.e. a long brake pedal for the initial pedal press after a corner. It can depend a lot on the age and quality of the hub, piston seals, and whether or not there are any anti-knock-back springs in the caliper (unusual on road cars).

    If you're unfamiliar with pad knock-back, what happens is when you corner there will be a certain amount of flex in the hub and a certain amount of run-out from the hub and disc that contribute to the disc running slightly off-axis, and that pushes the pad and pistons slightly further back into the caliper. The next time you press the brake pedal you have to overcome this extra distance before the pads are making good contact on the disc again, which can be a bit disconcerting. We see it all the time in the Caterhams and a lot of people get used to giving the pedal a light brush with their left foot along the straights. The ideal solution is a floating disc or caliper (standard road car calipers 'float' on sliders) to accomodate for the flexing.

    Interesting stuff, my mate with a Clio RS3 has just upgraded to bigger 2 piece disks. Being radial mount it gives me the option to upgrade the disks in the future to a 2 piece style and maybe go bigger diameter. I'm the limiting factor at the moment so may be a while before i start to see issues.


  2. Just found the forum and thought i'd say Hi! I'm looking forward to seeing what people are doing with their cars, maybe get some ideas. I have owned my 86 since November and absolutely love it.

    Got some plans for it and have started doing afew small things so far like the OEM armrest and debadged (front and rear toyota badges are going back on sprayed black).
