skidding all over! how does everyone feel abou changing from drums to discs?

my wifes car and a lot of my customers cars did the same thing its an easy fix happens a lot when doing new brakes but so now I do this before installing any brake shoes but can also happen later once your worn your brakes in some. try this and let me know if it worked.

take apart the back end to get the drums off, next go find a rasp or a hefty file and grind down the top and bottom edge of the brake shoes. don't be shy take them down good I normally take them down till I have no 90 degree angle on the top and bottom of the shoe.

what happens is when you slightly apply the brakes the shoes start to work, no rear brakes should activate before your front do, that's why normally you replace your front pads atleast twice before you replace your shoes. anyways when you slightly apply the brakes that 90 degree top and bottom of your shoe grabs first on the drum lining and instantly locks the wheels up and harder you hit them the harder they dig in.

that process is called chamfering and it's done on most disc brake pads (the good ones anyway) from the factory, I've never seen anyone do it to a brake shoe but it makes sense.

thanks for sharing.

Something similar happens with bicycle brakes but it's the other way around. You usually have to physically bend the caliper so that the shoes touch in front first. Anyway, I'm glad I came upon this thread because my XJ is doing the same thing. I'll be breaking out the file in the morning. I was tempted to just disconnect the back breaks in that I had already flat spotted a tire because of this. Thanks xj_redneck!

also check you ebrake cables make sure there not stuck or to tight.

another thong run 80 grit sand paper over the whole surface of the shoe and clean up the edge of the drum aswell.
