Bias valve - Ben - 29-02-2012
Hi guys,
Changed my rear beam from a drum one to a gti one around a year ago. My drum brakes had a bias valve in the line and also a compensator.
The new beam had neither of these and I just assumed that on the older cars the brake lines just went straight from the front into the brakes, so this is what I did.
I've recently heard a couple of people saying that the bias valve is very important, and I'm thinking maybe I shouldn't have removed it? :/
Anyone fancy explaining what should be in a braking system?
Ben

I've taken the compensator off mine and it's fine!
Do the back wheels lock up when you break?
Re: Bias valve - Ben - 29-02-2012
I took off something else as well though which I think was the bias valve. My rear brakes don't lock up no but as there's no valve in there now the back brakes must be getting the same pressure as the front?

I can't completely remember what I did when I swapped my rear beam over. Definitely took the compensator off. Someone will be able to give you a bit more info then me!

Cool at least I'm not the only one it can't be too bad! I braked very hard earlier and it felt nice and controlled and stopped very quickly, so I'll go by that and what you've both said and leave as is. Thanks for the replies (Y)

Bias valve is a compensator and you dont need one, I dont have one on my dturbo

Mine was sticking didn't notice it in a straight line but I came round a bend and had to brake hard!!! That wasn't fun. Wd40 and a hammer sorted, though I think the ph1's is a load sensing thingamebob
Re: Bias valve - Jacko - 01-03-2012
Yeah I had the same problem Jonny. big hammer FTW!
Re: Bias valve - Connor - 01-03-2012
