can anyone tell me what i need to do to my 1.2 8v merit to convert the rear drums to discs i have a astra gte donor car.
Is there anything special i need to do for a bias valve and what do i use for the handbrake.
I know this has been said often but i have used the search and cant find the information i need.
cheers andy

You need a conversion kit, about £100
PVD sell them, but dont expect rapid delivery.

m2rv_h, beardy, daimob have all done it.
as far as i know you bolt the astra stub axles onto the corsa beam, also some welding is required for strength, then you need a nova short handbrakes cable.
im not sure wat happens about the brake pipes though, never heard it mentioned before so i assume that they are a direct fit.

here goes...
grind stubs off astra and keep the mounting plate
grind plates off corsa
line up astra plates on corsa axel
weld them on
redill holes
bolt astra disks onto corsa beam with nova alen key headed bolts
refit onto car
rebend brake pipes or get new ones made
use corsa main cable, early nova short
blead brakes etc and check all lines up ok
