Bronco is pulling when breaking!!!! any help

[calger]

Bought a new bronco in Las Vegas, and drove it home to Illinois. In MO smoked wheel bearing, spindel,hub, and a few more things on the passenger side. Be for i did that, the Bronco drove like wife's 2007 Honda, well almost. But really it was great, but after the shop fixed or did not fix. It now pulls really hard to the left when i brake. And it kinda feels like it pulls when i punch it hard, and also when i let off the gas with out using the break.
What am i looking at?

dISK OR DRUM BRAKES?

could be calipers (or drum mechanisms) aren't backing off, maybe they didn't get lubed well or put together right?

After it has set for a while take it for a drive use the brakes as little as possible. Stop on the side of the road. If you can reach through the wheels touch the rotors or drums. If one side is much hotter than the other then they may not be backing off. Wheel bearings too tight on one side could also cause a heat difference. Check wheel bearing torque to see if it is the brakes.

Unless they did something silly like drop it off the lift you are rather limited in what was touched/changed. Sounds like one of the steps along the way was not completed properly.

Since brakes werent an issue prior to the bearing problem I would pull the wheel, pull the caliper from the side it is pulling to and spin the rotor. Does it spin easily or does it take effort to spin? Is there any grinding or other noises coming from inside the hub?

If that seems ok, then I would have to go with a brake problem. Either you have a bad caliper that wont let go of the rotor all the way or possibly a problem with a bad brake line or proportioning valve.

At least there are a couple things to look at, but I would suspect the bearings in the front end more than anything else at the moment...and they are the easiest to check IMO.

Pulls left, right brake isn't living up to it's function.
Whatever the shop did to the right side wasn't quite right.
Check the caliper to knuckle clearance. If it is a GM brake conversion (a lot are) there may be contact between the caliper and the knuckle. That would occure if they changed the caliper.
Another option is they changed the pads, but only on that one side. Lazy mechanics. Different pads bite the rotor differently. So there may be a pull there.
Recently there has also been reports of different grades of cast iron in the rotors causing a pull.

Whatever it is, it is generally simple. For the most part all the brake parts for left and right sides interchange. Just swap parts one at a time from side to side until you change the problem, then that part was the problem. Just check the clearance first.

Note that calipers will interchange side to side phisically, but doing so puts the bleeders facing down so you cannot bleed them. The bleeders need to be on the top so you can bleed the trapped air bubble of the top of the caliper. To get around that if you are trouble shooting is to bleed the calipers with a block of wood between the pads. That lets you position the caliper with the bleeder facing up, get the air out, then remove the wood and install the calipers on the rotors.

hey thanks guys.
Hey Broncobowasher, that was what my buddy thought. I am not 100% sure but i think the guy i bought it from did say that it had the GM Disc conversion. When the shop were looking for parts, they might have found some D44 Disc brakes. Well that's what my best friend thought. Is it easy to tell the difference. Well thanks for the help.

Look closely at your hard lines. I had a problem like this for quite a while. Drove myself nuts trying to figure out what was wrong, only to realize that one of my brake lines was squished flat. $3 later to replace it and my brakes were back!;D

What parts were replaced in the right front?
