...was trying to fix my brakes today, front ones no problem, rear ones are shit.
followed the step by step instructions in the cosworth manual but nothing realy happend on the rear ones.

when I press on the breakpedal i have pressure but when opening the rear brake bleed valves there's NO oil coming through

abs pump is running, i can hear it 'buzzing' as described in the cossie manual.

calipers are in very good condition and i fitted some brandnew hoses, oil is also brandnew

what can be the problem ?

thx in advance
