Title: Brakes grabbing Post by: holdsy on June 08, 2009, 02:22:16 PM Hi
I have an Fc with a HR disc brake front end fitted and a HR diff with drum brakes, the problem i am having is the brakes seem to hold pressure on on their own, is the problem with the mastercylinder not releasing the pressure or is the remote booster the problem? Any advice will help Cheers Allan Title: Re: Brakes grabbing Post by: mcl1959 on June 08, 2009, 04:41:01 PM What sort of master cylinder? Could be swelled brake hoses which is what I would check first. The calipers could also be gummed up which is what I would check second. There is a valve in the end of the stock master cylinder which can get gummed up - 3rd thing to check. Not likely to be the booster, but that would be the last thing to reco if all else is OK.

A drum brake master cylinder has a residual pressure valve which you don't use on disc brakes. This valve will hold pressure on the discs and make them drag.
So long as you have ordered a disc brake master cylinder, this should solve your problem. Ken |
