Hard braking

[Sparky13126]

Hey everyone, i have an 84 k5, under medium to hard braking it pulls to the right. Any ideas? I am told this is normal due to bad design. I don’t remember this to be true back in the day. I appreciate any and all input.

Any recent service? You could have one caliper not working out the other grabbing. Also need to check the pad and rotor condition

No, no recent brake work. I will look into though. Thanks

Check the fluid and bleed the brakes as a start point, do the inspection while you are at it

does it dive to the right or just kinda drift that way? Rear brake adjustment has some sway over drift. Dive is more likely front caliper hanging or possible a hose, gm hoses are notorious for the inner tube pinching and acting like a check valve.

While you are checking your hoses and pads, check your ball joints too.

Brake pull usually goes to the side that is doing more "work". So if it's going right, look at the left front. Like others have said the rubber hose may be collapsed not allowing fluid to move to that side. Could be a stuck caliper.

The rears can play in with the drum adjustment. Or you can have a axle seal leaking 80/90w gear oil coating the drum on the left rear.

I'd pull the wheels and look at all the brakes. Look at if the pads are wearing evenly inboard to outboard and side to side. Look at hose condition, if you have oem hoses that are 30+ years old they are suspect by age alone.
