Describe you car and brake setup and say which wheel(s) brake first? I have a stock 1990 mk2 8v gti (mk4 rear calipers) The rear wheels both lock up when doing an emergency stop - took me by surprise.
They really shouldn't, fronts should lock up first. sounds like either your load sensing valve is adjusted wrong or is faulty. Is it lowered? Anyone mess with the brake lines off the master cylinder?
It's running a 16v 22mm master cylinder. Whole car is stock. Both brake lines come off the RHS off master cylinder (when sat in drivers seat looking forward) Other two master cylinder outputs are blanked off with bleed nipples. Does that sound right??
adjust so the slack is just taken out of the spring, and make sure the lever arm is nicely spring loaded and not just flapping around
Thanks - i'm not familar with mk2 golfs (I'm better with mk2 polo's) So not sure where the compensator is or exactly how to tweak it - is there a faq somewhere?
under the car in front of the passenger rear wheel, theres a spring loaded valve attached to a beam bracket. the spring has a slotted hole, if you lower the car it makes the valve react as if you have a heavy weight in the back of the car increasing rear brake force. loosen it back off as I say so the slack is just taken out. the factory adjustment involves hooking up pressure gauges inline with rear brakes so not easy to DIY
They're may be but it is a simple as what rubjonny says. Its attached to the rear beam on the passenger side. You'll see it, and its spring, with brake lines going to located under the car, near where the beam attaches.
