crazy brake idea
RickRick - 13/7/09 at 06:42 PM

Ok who thinks there might be the slightest chance that if i mounted somthing like 4 pot motorbike front calipers and disks onto the rear of mnr it could work, would they be close enough power wise to cover with balance bar adjustmeant, would they take the heat generated or not?

No reason why not for the rear brakes. We used motorbike brakes all round on our single seaters.

Bear in mind most need floating discs though so its a custom machined hubs jobby.

It'll definately work if you're going to do hillclimb/sprints (60 sec blasts then plenty time to cools down) but for normal road use I don't think they'd cope so well.

yer i think i could manage the custom hubs, to mount floating disks, and to replace the thickness of the disk, also mounting the caliper should be simple, as the calipers are quite small, getting the balance right might be hard work, but sould be achivable i just have no idea if they would cope with the heat they might encounter

You'll still need a handbrake as well.

They will cope with the heat etc ,wouldn't even need to be 4 pot, as they do next to sod all on a se7en

cbr600 discs and pug106 calipers,(which have the handbrake facility) 5yrs of trackday abuse
with no problems to report.

What about Inboard Brakes on the Drive shaft instead of Out at the Wheel Bit like a Kart?

Didn;t some of the old Volvo's or saabs have inboard brakes?

i've got freelander diff, so no bolts anywere near the diff output, also there's not very much space around the diff

GB Engineering do parts for fitting Fireblade front calipers to Sierra rear hubs including slimmed down discs.

I tried that set up, it was a pain.
Slight movement in the output shafts made the discs rub on the pads (very annoying noise, especially when cornering) and grease from the c'vs kept getting on the discs.
Might be ok with a newer wear free diff, and some sort of boot over the cv's, but i junked it due to the hassles.
The discs also have to be very small due to space issues.

What width are the disks in the pic above? Surely the peugeut calipers were designed for a 9mm disk where most bike disks are more like 4-5mm?

Are the peugeot calipers alloy?

if its a bec, mount a handbrake disk and spot caliper in the tunnel like bob carter did and then just use the hydraulic calipers for the footbrake.
