As title, I need to fit Wilwood 4 pots to the back of my Corsa and am inquisitive as to what is needed? I know the rear beam needs converting but as the discs are aluminium bells where does the handbrake come in? I know the standard rear disc brake setup has a fluid system for the pistons but a mnual drum operation for the handbrake! Where does the handbrake come in on mine? Can anyone recommend somewhere in a 60 or so mile radius who's welding is the absolute tits?

Obviously the rears should toe in around 1 degree and I dont want monster negative camber! I can get those two perfect but are they likely to seep due to warpage/expansion from welding? :confused:

not too sure of the ins and outs of corsa beam conversions, so i shall steer clear of that side of things.

there is no handbrake mech on the 4pots,and also there may be some offset fitment issues with the bells of the disks!

all i can suggest that may be useful is buying a pair of rear handbrake calipers and make some custom brackets, ive seen this done on escort rally cars.

also surely to god 4 pots on the rear are gonna send you backwards into the scenery the first time you brake slightly out of line???

I have considered the offset thing already but thats easy enough to check and rectify!

Even for a setup that came from the back of a Calibra there is no rear handbrake setup? May have to go down the route of a seperate callipers as you say, any suggestions? I know the frog cars like them!

I will go down the bias route if needs be, but dont want an in car adjuster as it will be a daily driver!

hi spec do a caliper for the rear that has the h/brake built into them which runs from a cable. also the ap calipers on the vx220 are like this aswell.

Ah, so the bit that gets welded on will retain the drum section? I assumed the disk/drum was a 1 piece unit? Cheers Kenny! :beer:

If it uses the hub and the bells bolt on then its all great! :D

:beer: I read that a bit back but hope to retain Wilwoods all round, just for uniformity! Cheers though Tash! :beer:

there are rear brake conversion kits for the corsa, basically its like £40 for a metal plate i think an some instructions, and you cut something off, weld the plate on, use an astra rear hub and astra rear caliper

Yes but thats a common thing, the problem arises due to the calliper and disk/bell setup! :(

Cheers anyhow MarkyG

Not sure, will have to check! Is that steel insert a common thing then? You mean like a liner within the bell that acts as the friction surface?

imo 4 pots on the rear have no performance gain at all you will have to have them woeking so light with a bias valve they might as well be standard calipers

unless your doing it for looks then they look kool

To be honest I ws never going to fit rear discs but as they were sold as a package with the fronts it would be rude not to! lmao

I know the rears are only responsible for about 15% of braking so fitting them is more of an aesthetic thing rather than full on performance, but they will look the mutts nutts! lmao

The rears are the same size as the front Wilwoods I just sold! lmao
