Ford rear brake pressure valve
Motty - 4/2/04 at 07:43 PM

The standard unit from the bulkhead of a Sierra, can anybody tell me what end is the brake fluid in end please and does the "nose" point un slightly or down? I know I haven't explained this at all well but hopefully you know what I mean.

The best place to position the brake proportining valve from the sierra is in the bin, you don't need it. If you must fit one use the fiat one (uno I think) as they are adjustable and the sierra one works on the suspension angle change which you will not get in a locost type car.

yours, Pete.

it would be dodgy to use it. it works on G force and is VERY sensitive to mounting angle. get it wrong and it wont work right.

fiat uno or mini proportioning valves are best. Some people say you dont need them, others do. its prob dependent on your car wieght and brake types

Absolutely correct, Steve. Plus how will you know when it doesn't work?

Plus a whole raft of other variables, e.g. wheel-base, height of c.o.g., weight distribution, friction quality of pad/shoe lining etc. etc.

Alternative valve suggestion, Motty - use one of those screw-in valves used on the Mk3 Fiesta mcyl. Not adjustable, but uterly reliable.

so this means another part of the avon book is wrong ( it shows one of the sierra brake regulators fitted sideways in the back end )
i am begining to get a complex about the avon book

I think the way Tiger have mounted it, they are hoping that it will limit the pressure constantly, not just under heavy breaking, because I think it is mounted backwards aswell!

I was never intending the use the piece of shite!

I've now gone for floor mounted pedals, and have a spare brand new Uno valve.....

"so this means another part of the avon book is wrong"
