rear bias braking problem?
« on: 11 March 2009, 15:44 »
my golf seems to be locking up at the rears when braking. even when first getting into car and reversing out drive if I brake I hear the rears coming on. any ideas? My pedal doesn't seem as good as my neighbours identical car but it passed MOT just a few weeks ago.

when I got my brake bled they said they freed that valve thing off but maybe its still jammed, might take it back for a check. Still wondered why pedal ain't as good as my neighbours though?

The load compensating valve is probably worn out. It moves about every time you go over a bump, so after 20 odd years it'll be a bit tired.

It can also be a cause for seized rear calipers. If it is not giving enough pressure to the rear, the calipers will seize up from not being used.

I think they are around £60 to replace.

Cool, the rear calipers are brand new and giving the opposite effect of too much rear braking and nowt from front. Is this £60 from VW or another?

Someone (I think rubjonny) has done a guide on here about adjusting the rear bias valve.... I adjusted mine as the guide said (as mine has mk2 rear brakes!!) and it was just a matter of modifying the spring (I cant find it now but it's defo a mk2 section bit)

found it http://www.golfgtiforum.co.uk/index.php?topic=27064.0

Also, if you have recently lowered the car without adjusting this compensator then by default it will give you heavier braking at the rear
