Now that I have done with my timing belt replacement, I still have a nother problem. When I step on brake the car pulls to left at any speed. I can see the steering wheel truns to left. I thought the problem is from calipper. I replaced both calippers and still the same. Rotors and pads are low too (already ordered). Any idea what cause that? I bought the car for my son for $2500 about 3 months ago, he'll be driving it to college for next 4 years, car runs fine.

It is a good idea to replace the rotors and pads when replacing tired calipers. It is possible that one rotor is thinner than the other. You could still have a little air in the brake line. I would flush the entire brake system with a quart of Dot4.

When you put the new slide pins in, did you nicely coat them with brake grease? Order a new pair of spring clips while you are ordering. Then make sure they touch the pads.

Replaced rotors and new pads. Problem still exists but I found out what was causing it. During rotors replacement, I found the control arm bushings were bad, the rubbers were cracked and the arm was moving back and forth when I pushed the arm. I ordered the bushings and replaced them and car is fine now. It's pain to replace the bushings. There're super tight.
Thanks
