any one know about the twin rear caliper setup?

i know stromba had valver front brakes mounted on the rear along with the original rear caliper. so he could use one for his hydrolic handbrake.

my question is how are they mounted/fit ?

best thing to do would probably be drop him an email he usually helps when asking about things like that

why??? it's hardly a heavy car, if you want to inprove braking to the rear, adjust the bias.

Burp on CS has had trouble with reducing the bias to the rear on his 172 since re-plumbing and adding adjustment, the calipers are perfectly capable, they just dont get asked to do anything

how can the rear bias be adjusted guess its the threaded adjjuster on the valve but which way increase the rear brake performance

why just use the standard calipers and two handbrake levers..one hydro working the rear footbrake calipers on a handbrake otherwise you increasing unsprung weight which is a huge no no.

Like others have said, just plumb into the orginal calipers

Mines been no problem for the past 2 years :D

Standard rear calipers are wank.... Mine will only just about lock with a hydro handbrake

The piston on an front RT caliper is much larger and suiited to locking the rear wheels... and weight wise.. if you have to have extra weight might as well put it at the rear and low down

Standard handbrake and caliper set up for brakes and extra front RT calipers bolted on and plummed to hydro handbrake

What size master cylinder were you using on your system winston and which style of handbrake (vertical or normal)

Like Iv said above no problem with mine using standard calipers, locks up just fine

Sounds like they're ****ed. Burp disconnecet completely to stop the back locking up and overtaking the front yesterday. Nothing wrong with stock when they work
