'97 sunfire pulls hard to the right when brakes applied. Changed pads and rotors on front end and bleed brakes but made no difference. Any suggestions?

Bleed your brakes. Start with the right rear then left rear then right front then left front.

rotors need replacement

make sure that the calliper body is free to move on the support pins
the pins are there to allow the calliper to centralize on the rotor
if the pins are seed up then when pressure is applied to the piston the calliper is pulled sideways but then keeps that pad in hard contact with the rotor
as there is no check valve in the master cylinder for disk brakes, there may be a problem in the compensating port for the disc section that is keeping the disc brake section on

did you bleed the system after the install? and did you remeber to adjust the e- brake cable?

will try to help. when front wheels shake while applying brakes and you can feel shake in steering wheel, front brakes and rotors need replacement.rotors are warped,if you replace front brake pads, it will return[shaking when you apply brakes] suggest that you replace front rotors[both] replace [both]front brake pads. cost? i would charge [brake pads cost $55.00] labor,$60.00] total $115.00 thank you for choosing fixya.com

I think you should get the Tierod ends checked. When you get a Front-end alignment, the mechanic will check them. Although you turned the front Rotors, when you start Braking the front tires can wander differently than when they freewheel.

Sometimes you can get a rust problem on the Rotors that were just made shiny. Moisture on the pads imprints a rust blotch on the Rotor and they grab at the rust until the rust wears down. Then they are ok.

When the rear Rotors were replaced check your bill and see if the Emergency brake shoes were changed. The E brakes should have been adjusted when the Rotors were replaced. The Shimmy you describe can also be the ABS working. The ABS is a pulsating Brake action.

Get your front-end checked first, then as the mechanic road tests it when the Alignment is complete, he can judge the brakes.,

Check for unusal wear on the new rotor,skips/hard spots/uneven wear. If you find any of those things it would either be the new roter is out round,or you have a brake caliper piston sticking on that side of the car. You may bleed that side of the car to remove any air trapped in the system. Doing so will remove any air trapped behind the piston. Jack up that side of car and block the wheels to keep it from moving. Remove the tire and have some one to step on brake pedal while you are watching the piston, this will cause the piston to expand. Have the second person to take there foot off the pedal and the piston should retract. If all of this checks out to be ok, then turn the rotor slowly to see if it has a high/low place on it. If so then the rotor will have to be turned with a brake lathe to even both sides of rotor. If you just purchased these rotors then take the bad rotor back to the store and exchange for a new rotor. hope this will help you.

Spongy means air present in the hydraulic system,I recommend check and recheck all of the brake system areas where air could enter(master cylinder,fittings,calipers,etc.)and bleed the entire system again.
Good luck !

Air in the brake system bleed the air out

Sounds like it was pulling before the brake job...if so the only thing you didn't replace was the rotors, I assume you turned them? and did you see hard spots on the rotor? discolored area that didn't cut the same......switch the rotors left to right and see if the problem moves or just replace them if they've been cut twice.
