hi guys, i have a 1973 cj 5 304 and the breaks are grabbing or pulling badly to the right , so bad that if i press on them hard it will almost run me off the road. what should i be looking for ????
Good possibility your right side is doin what its supposed to and your left aint. Check the wheel cylinder on the left side to see if its leaking and/or locked up. May be as simple as rebuilding left side cylinder. Several other possibilities but I'd start there.
My drum breaks have served me well over the 37 years I have owned my jeep. When your jeep severely pulls to the right it usually means your left caliper is out and not working. Look inside your master cylinder and see what the level is.
but if you ever owned a chevy pickup you might also check the rubber brake hose that goes from the frame to the front brake.
on the chevy trucks the inside of the rubber brake hose would deteriorate, as you pushed the brake pedal, the brake fluid would flow to the wheel cylinders, when you released the brake pedal, one brake cylinder would release as normal, because the fluid could flow back to the master cylinder
but the wheel that grabbed, the interior of the hose would not let the brake fluid flow back to the master cylinder. it would pull you right off the road or into the other lane of traffic.
but looking at the brake parts, every thing looked good, was a real pain to fix, except for an old mech that had seen it before.
would sure wake you up, as my old chevy truck, would almost jerk you off the road,
do not drive that vehicle on the roadway until you fix it, you could kill yourself or someone else.
let us know what you find.
a vehicle that will not run will not hurt you, a vehicle that will not stop, can kill you or someone else and it might be me.
It is going to pull to the side of the good brake, so look for something on the other front brake. A bad rear brake won't cause a severe pulling problem. My 2002 Safari van was doing the same thing and it turned out to be a bad brake hose. As explained to me by my local NAPA parts guy, the hose lining can separate and collapse. How that kept the brake from working I don't understand, but once I replaced the hose on the side opposite to where it was pulling, problem solved. GM service guy wanted to change the caliper until I told him I just put new calipers in trying to fix the problem. They wanted over $200 to change the brake hose but they didn't have in stock. Picked one up on the way home for $17, about an hour later it was fixed.
If he has drum brakes all around it could be a bad brake hose, worn shoes, broken hardware , or something as simple as they're out of adjustment. (Which is what I would check first with drum brakes on all four corners)
The auto adjusters are only half reliable in my opinion.
How far down do you push the brake pedal before you start to stop?
With the wheels in the air you should feel and hear slight dragging of the brake shoes. If you spin the wheel and hear and feel nothing adjust them and go for a drive.
You know you got then right when it takes a little wiggling if the drum to get them off. If they just pull off they are nowhere near correct adjustment wise.
Yea, could be one set of shoes out of adjustment. BUT, is the pull constant, or does it jerk right and then pull straight after the initial application of the brake pedal? If it fits this description, it is likely a brake hose.
