2 Possible Major Problems!!! Help!

1989 YJ jeep wrangler 4.2 5speed inline6

My brakes are really sticky, they wont stop dead on like they use to. I have replaced the brake shoes in the front, the hubs in the rear. Bled the brakes and they still are sticky bad. What could it be??

The second problem is a killer wining sound when its in first second and low 3rd gear. It sounds like a car with turbo. Im not sure what it is but i know its going to be a problem in the future if i dont try and fix it now.

As always thank you for any input.

My guess on the brakes would be calipers. Check/change fluid in trans.

Two possibilities. One. Calipers need rebuilding. Two. Your brake lines have collapsed.

One or both front calipers could be hanging up. Could also be the master cylinder and/or proportioning valve. Also, have you checked your wheel cylinders for leaks.

the brakes you can just exchange for about 30 for new calipers. make sure your back brakes are adjusted correctly. the turbo noise your hear might be from the intake. you might need a new filter or something. or those gears are putting some stress on it causing it to need more air and gas

I agree w/the others on the brake deal. If you have an aftermarket air intake system or a TBI spacer, then that causes a whining/whistling noise. Since you didn't mention these I wanted to bring it up; not trying to insult your intelligence, just starting w/the most obvious and work from there.

What he said about the noise - I have a CAI, and it whines like the devil at some speeds and throttle positions...

In dog beers, I've only had one.....
