Craigorypeck - 11/3/13 at 10:01 PM

Capri atlas axle running standard drum brakes and 15" Minilites, whats needed to convert to discs? cosworth rear discs and calipers gets thrown up on a search but which? 2wd or 4x4 calipers and discs?
Is there a possible bolt on bracket available without welding?
Whats needed to connect up handbrake?
Will be sourcing second hand parts to keep cost to a minimum.
BTW i have 283mm discs and 4 pot cosworth calipers setup at front. Plus a landrover master cylinder, will this suffice??
Any help would be great!

Hint Search eBay on "rear disc conversion Ford"

done that, kits are £500 quid and the listings dont give too much away as to what they are actually selling ie. standard cosworth off the shelf parts. just 248mm disc, solid 10mm, single piston caliper etc.

maybe some knows what I need and willing to help?

Look again £50 for brackets + discs from your local motor factor + 2nd hand callipers + seal kit.

You don't need massive or vented discs on the rear they only get 1/3 of the heat energy that goes into the front brakes, for predictable braking you want the front brakes to warm up at the same rate as the fronts

And I would consider a bias pedal box

righto so im on the look for non RS sierra calipers and 253 non vented sierra discs, an xr4x4 handbrake cable may suffice with some fettling too.
I aint got the funds for a bias box and dual servos and would like to keep the servo.
How are bias valves plumbed in? and are they any good?
Thanks

edit, it looks like some valves are adjustable and some not, some have 2 connections some have 4..? any info for me? ta

You really don't want a servo just design your pedal to give a decent leverage ratio and use a smaller bore master cylinder (Fiat)

Reducing valves just fit into the main rear brake pipe - be sure to fit the pipes correct ports. The ones branded by a major race car brake manufacturer aren't suitable as the minimum operating cut off pressure is way above what your car operates at, a Fiat Ritmo/Strada?124/Lada or Uno valve mounted on a special bracket is a common choice.
