what have done wrong??

I finally filled my brake system tonight, I've installed 9" servo/ m.c, complete new copper lines, goodridge hoses, g60 calipers/ discs( new nipples), new rear cylinders/ pads. The thing is they're ****e!! my racing bmx stops better!!

I filled the system, using a gunson easybleed kit. Used 1 litre of synthentic dot 4, ran through all air out of lines. So what have i done wrong?? It really has cheesed me off, I've spent a f@cking fortune, not including my soon to go in 20v, ko3s etc etc!
The only thing i can think of is, that i kept on the 9" clevis, but only because it had the hole there for spring, but i trimmed off 10mm from the 9" piston rod thread.

cheers boys.

Is the problem due to the mechanical leverage not acting on the master cylinder, or the brakes not bled properly?

I'd personally not use an Easibleed kit for the rears on a Mk1 Golf. They have either a presure reducer or a load compensating valve. Brake pressures are in the region of 2000psi. The valve greatly reduces this. So I don't think the 30psi or so of your spare tyre is going to worry it too much. Do it the old fashioned way, with a 1 way valve on the bleed nipple, and you should be okay. If its a new MC then pumping the pedal will be a non issue if done slowly.

Have u tried adjusting the brake linkage bar? Not sure if that'll do it or not :/

Just to give you another view - I use Eazibleed every time with great results, that's with rear compensator (clamped) or bias valves fitted in the engine bay…

Like Paul said, is the operating rod actually pushing te master cylinder via the servo ? What gap did you set between the rod and the aster cylinder ?
Are your rear shoes adjusted to be close to the drums ?

if they are second hand parts the master cylinder may be shot?
