What size torx or allen wrench is used to change front brakes on a 1997 sunfire

SOURCE: Brakes pulsate real hard

That is just the ABS system at work. It is supposed to prevent your wheels from locking which often makes the brake pulsate, especially in wet weather or or snow or ice. The only way to really stop this is to disable to ABS by unplugging it and removing the fuse. This will make the ABS light appear in your dash, but your brakes will stop pulsating.

You need a 3/8" allen wrench, it would be best if you had a socket allen wrench which would work quicker with a wratchet. If you ever have to do a wheel bearing you also need a T55 Torx socket. Hope this helps!!!

Are you talking about the Power steering pulley? Unbolt the pump, It is held on by two bolts and they are accessed thru the holes in the pulley. Just unbolt the pump and move it out of the way. Leave all the lines attached to it.

SOURCE: how to change front brake pads on a 1997 pontiac

first, break the lugnuts loose on the front wheels, but don't take them all the way off. Then raise the front of the vehicle with a jack, and support with with blocks or jack stands. Turn the wheels to one side so you can see better. Check your brake fluid level, and remove some from the reservoir if it's full. If you don't do this, it WILL overflow. Start with whichever side you turned it to, grab the caliper, and pull it towards you with a good strong, even pull. It should move slowly, and then stop when you feel it bottom. If it doesn't want to move, you can use a flat screwdriver and pry it towards you by inserting the head of the screwdriver between the brake pad and rotor on the side closest to you. You can also use a c-clamp to compress it if available. Look on the back side of the caliper. You should see two bolts that have round heads, and take an allen wrench. You will need to loosen these bolts, and remove them. be cautious, you don't want to break the rubber bellows that they go into, and you also don't want to get dirt on them. These bolts hold the caliper on, and also allow it to "float," in essence letting it move with the rotor. once these bolts are out, the entire caliper will lift off. Pull the brake pads out, and put the new ones on; coating the BACK of the pad with the anti-squeal grease before installing. Next, put it all back together just like you took it apart. Turn the steering wheel the other direction, and repeat on the other side. When you're finished, make sure the brake reservior is full, start the car, and push the brake pedal in. It will probably almost go to the floor, but this is normal; the calipers are just adjusting. press the pedal again, and they should feel normal. Have fun, and enjoy the savings from doing brakes yourself. This is a perfect starter job.
