1985 110 Front Brake Calipers

Another couple of thing forgotten about county stoppers.

There are different size shoes for as your drum wears. Very important that you get the drum cam correct ( adjusters) i start with the drum off and a ruler, very important is the cam by the slave, get this wrong and you will be pinching fluid from the fronts.

This is where someone pipes in as says, split system. Which it is.

Second forgotten thing

on the fire wall there is a balance valve thingy. Every one I have seen has been stuffed. its purpose is to equalize the pressure from front to rear. This is done by a piston in a sleeve. One side of the piston is front the other left. If your backs are out of adjustment the piston will be pinched over which takes fluid from the fronts. Add to that the O rings on the piston are probably shot which lets fluid pass from the fronts to the rears.
wooden brakes and slow stopping.

about 300 bucks for the balance valve, or a couple of O rings, if you can get it apart

Not sure what you mean by "start with the drum off and a ruler ,and "the cam by the slave".
Both cams are equal distance from the slave, and I'm not sure what you're meaning to use the ruler for.

Good info about the balance valve. When did LR stop fitting that - was it when they started fitting rear discs?

Matt - have you got new lines on yours (as well as the Defender booster and rear disks)?

ops i was thinking of some thing else,
i mean the spring by the slave is stronger than the other spring. if you doint have the cams adjusted correct the shoes retract to far pushing the slave piston back in. this then pinches fluid from the front Ver the balance valve.
the old school way of nipping up the cams then baking them off is not really the most reliable way to do these. with the drum off i measure the dia of the drum and then the placement of the shoes to make sure they are lined up well IE one shoe is not higher than the other. may sound a bit over the top but i can chirp 33" 12.5" on the black stuff.

as for when the balance valve was first fitted and if it was not, i have no idea. i do know that there are 2 different model valves, one larger than the other. i doint know why.

i fact i am so happy with my disk drum setup that i given away all ideas of changing to disks and the disadvantages of disks, in a mudless and dry SA
