binding wilwood callipers
nib1980 - 6/5/11 at 07:42 PM

hi all,

went for and passed MOT today but on the way home my new wilwiid callipers appeared to have bound on.

investigation shows the fluid is unable to leave once its in the circuit. i.e it can't return to the resouviour.

anyone got any ideas?

could it be a duff Master cylinder?

many thanks

p.s. there all new...

no play in the rod from the pedal to the cylinder, there should ne some play otherwise the return circuit will be partially closed and the brakes on this will get worse with the fluid heating and expanding

Also check for a sticking brake pedal

when you say some play how do you mean?

there should be a small amount of movement before the rod pushes the piston therefore free movement there could be a stone under the pedal
