Handbrake turns...

[jimnielsen]

arjunior... I have just completed my 166 caliper upgrade (just waiting for the new wheels to be delivered before I change over...) But now I have the near new original front brake rotors and some wilwood dynalights so I was thinking how that would work as rears...

two problems - 1. handbrake. I NEED a handbrake - my trailer (that I made for the Q4 has a sloped back and the car rolls off too easily without one) Its just too dangerous otherwise, the car will either roll off on me or someone else.. so its gotta have a handbrake of some sort. Hydraulic? maybe but how to implement it on a Q4 and what parts to use? Has anyone done one?

2. will need to be able to adjust the 'bias' on the front to rear pressure ratio. am thinking of replacing the single "bias valve" with a pair of sensible manual adjustable ones that have been used on racecars for ever... has anyone done this?

..Only 3 days to go till sandown raceway - weather says cold and wet!!

we had done this to a 75Turbo {manual adjustable bias - front disk on the rear axle - hydraulic handbrake with its own-separate caliper just for the handbrake and ...two {2} 4 pot piston calipers per side at the front wheels keeping the oem disks at the front too}. But it was long time ago and I do not remember the spare parts numbers we used. I believe the front calipers were from 75 V6 and the rear one the oem front one. The hydraulic handbrake was an aftermarket {not oem one} such as the adjustable bias. Later on we mounted double brake pistons too. No ABS was ever used. Quite impressive seeing double brake calipers on each wheel and incredible breaking power with this arrangement. Wish I had the time to arrange something similar for the Q4!

I think that the oem bias of the q4 is adjustable - not on the track though - but I believe it will be better to have an aftermarket pair of manually adjustable one located just next to the driver seat or just behind the gear knob.
