need help with this before I set fire to this damn car!!! She's a 1996 ph 1 spider. The brake compensator valve sprung a leak (and was rusted pretty much solid) so I have replace it. With the brake system in pieces, I took the opportunity to replace the master cylinder, too. The compensator is a genuine part, the brake cylinder a name brand, so I have confidence the parts are sound.
I've bleed the brakes through ad infinitum but still have a long brake travel before the car really stops - but only going forward! When I'm reversing, the brakes will stop the car almost instantly. What I need to do is get the same brake feel when I'm moving forward.
It seems to me that this must be down to the compensator valve and how I've adjusted it. Brake pressure must be fine, or I wouldn't be stopping so well in reverse. Likewise the friction surfaces. The effective braking in reverse suggests that the position of the compensator must be allowing more pressure to the rear brakes than it should.
Problem I have is that the manual requires the vehicle to be on its wheels, with a driver in the drivers seat, and then the 4.5kg/10lb pull downwards on the compensator valve lever to set the thing. I have to rely on getting the car on axle stands, so the wheels are hanging, which obviously will move the ARB, which will affect the load on the compensator in some way.
I know I need to adjust this, either putting more pressure on the compensator spring, and thus (I think) closing off the pressure to the rear brakes a little, and thereby increasing efficiency of the front brakes. I'm trying to avoid trial and error - i.e. up on the stands, adjust, down off the stands, quick test, back up again, etc etc.
I can't believe this hasn't come up before, but I can't find any real info on the actual adjustment in other posts. Anyone any ideas on how to properly adjust this thing? http://www.alfaowner.com/Forum/image...s/banghead.gif
