Finally got the custom rear brakes done

[Chris Wilson]

Finally got the brackets back from the anodisers today, so I thought I'd post up a few pics of my custom rear brake set up, albeit for my Skyline GTS-t, not a GTR. However, the principle is the same. I wanted to use some Aston Martin DB9 calipers left over from a brake upgrade, and they were a bit of a bitch to fit, needing some milling off the backs of the caliper radial mount area and a slightly more complex than normal pair of brackets milling up, but it's now done and they sit well on 330 mm x 25 mm AP discs. They were handy money, came off a brand new 100 mile car, and have the right sort of piston sizes and pad area, and are radial mount calipers, often easier to fit in a custom application than lug mount. I made bells out of alloy with integral drums, as a sap to the MOT. They'll work fine as a parking brake drum and they allow the use of proper lightweight race discs. A set of Performance Friction 01 compound race pads completes the set up. From experience these will work fine from cold, on the road, as well as full race usage. I'll fit them to the car as soon as I can spare the ramp for a couple of hours, which is helping make me a living right now, which, of course, has to have priority over "playing"

BHDave:

Fronts are done and fitted, see Pics Here and More Pics

Front calipers, like the rears, are Brembo, but with a much better pedigree, being off a Group C Porsche 962 Le Mans car, with fully floating discs, of, err, adequate size

One of the perks of being in the race car engineering game is your junk box gets some good stuff in it from time to time

[Bobjones]

Hell yeah...

what else is in the junk box...

[Roy]

What sized rotors are they? Can you help explain what effect an increase in piston diameters (4 pot on the rear...big Brembo 4 pot on the front) has on master cylinder sizing???

Does it simply result in a slighyly longer pedal, but with more feel as a result on increase in rigidity etc????

Well these look a bit noice

want to give me a set for my GTR?
