front brakes question

Hi,
A week ago i changed out my front brakes. After doing so it felt like the brakes were pulling to one side and the car was less powerful up hills and while shifting. I jacked the car up and only the passenger tire was spinning. I took the car in and they said the brakes were fine but they bled the system to make sure that it was working properly. Drove it around and seemed a little better.
A few days later i noticed it pulling way to the left. I jacked the car up again and the front drivers side was still not turning. It was acting like it was trying, but like the brakes were rubbing. I decided that i was going to change out calipers on the front left.
So today I changed out the caliper and now the drivers side turns like crazy but the passenger side doesnt move just like the left one use to. I drove it around and it is still pulling to the left. What is going on???
Before i took it to the shop I took off all the brakes and rotors and both sides spun fast so Im guessing that they both are suppose to spin close to the same amount with brakes installed? The car is a 2004 Scion XB.

Thank you for any help in advance.

Open the bleeder at the caliper and see if the wheel truns freely if so the caliper is at fault if not could be a bad hose. Look for any Toyota tsb's on this issue.

I think you have that logic backward. If after you open the bleeder the wheel spins freely, that means the brake hose is likely the issue (as the fluid can now escape through the bleeder rather than through the collapsed hose). If with the bleeder open the wheel still doesn't spin freely, the issue may be the caliper. Remove the caliper or pads and make sure the wheel spins freely.

OK thank you. I will try that this evening. Do you guys know if both wheels are suppose to spin at the same time or not? I've been told that I changed the caliber for no reason and the changing which wheel is turning now is just a coincidence. Thanks.

I'm guessing the car is front wheel drive.

Obvious question, but was it in neutral?

If the transmission was in park, the wheels should turn at the same rate when you rotate one. But the other wheel on the Scion will turn in the opposite direction of the one you're spinning.

Yesit is a front wheel drive car. I jack up the front on the car and put it in 1st gear and only one tire moves. It spins pretty fast but the other side almost seems locked up but spins a little and then stops. Now that a caliber was changed on that wheel that wasn't moving, it is spinning good and the other side isn't moving.

Do the pads move freely in the slides? I've had to do a bit of grinding on cheaper pads to make them fit right. Perhaps stuck pads could be causing your pull? Does it pull all the time, or only when you apply the brakes? Are the hoses twisted? A sticking caliper should be noticeable if you try to turn everything by hand.

Does it still stick if you rev the engine? An open differential sends all the power to the wheel with the least resistance, but both should move when revved up. At idle one or the other may appear to be sticking. If it still sticks, try holding the free wheel in place and see if there's any change (be very careful when doing this, you can seriously hurt yourself if the wheel starts to move).

I think you have that logic backward. If after you open the bleeder the wheel spins freely, that means the brake hose is likely the issue (as the fluid can now escape through the bleeder rather than through the collapsed hose).

-Rod Correct, too much of a rush, using a time limited borrowed computer, thanks for the catch. Shep

With the car jacked up and in gear, you should be able to spin either wheel. When you turn one wheel forward, the other one should turn backward. Its normal with the differential you have. If you jack it up in neutral, you might notice the other wheel moving opposite or not at all. That is also normal since you are letting the transmission spin as well.

Regardless... with the front jacked up (both wheels off the ground) both wheels should spin with the same resistance. If you try to spin one and it moves freely, and the other one doesn't, you have issues.

Using that info, can you explain the problem in more detail?
