Question about Scion xA

How do I get the caliper to fit back over the new pads, those being obviously thicker because they are new. I can't figure out how to get the cylinder on the caliper compressed to fit over the new pads. My car is a 2007 Scion XA.

The pistons on the rear brake calipers on many modern cars screw in and out unlike the front caliper pistons that just slide in and out.This is due to the handbrake using the rear calipers for handbrake operation. A special tool is normally required that screws the pistons back in so that you can fit the new pads. On many cars one side will be a left hand thread and the other a right hand thread. Some cars will be the same thread. These rear pistons will not just push in. Good luck.

Remove the new pads and put the inner pad back on then use a "C" clamp to drive the caliper piston back into the bore...THEN put everything back together and it will fit!!

    Forgot about the rears and you didn't mention if one or the other...yup...there's an inexpensive multi tool that fits on a ratchet handle available at most parts stores that's made just for rears..

Cheap and easy way to collapse a caliper


When replacing disc brake pads it is always nescesary to collapse the caliper again as the piston that presses the pads against the rotor is protruding too far for the (thicker) new pads to fit. Using screwdrivers and such can damage the caliper, so there are several tools available for purchase. I just figured I'd make my own.
Refer to the diagram
Use a piece of flat bar(B), more or less 1 by 4 inches and about 3/8 inch thick. Find a bolt and nut(A) that fit to each other, let's say at least half inch thick and about 2 inches long. Drill a hole in the flat bar, big enough for the bolt to fit through, weld the nut over the hole and you're good to go.
When collapsing the caliper(5), assemble the newly made tool(just screw the bolt(3) into the nut) place the flat bar(2) against the piston(1), use an old pad(4) and fit it into the caliper (this is something for the bolt to push against), and uncrew the bolt until the piston has been pressed back into the caliper.

How do I get the brake caliper hydrolic sleeve to go back in far enough for the caliper to fit back over the new brake pads?


Using the inside pad, remove the clip from the back of the pad. Place the pad back against the caliper in its original position and 524e65b.jpgusing a 7" C-clamp open the clamp to fit over the caliper and brake pad in the center. Then turning the screw end of the clamp slowly push the caliper back. Watch that it's going in evenly. Once the pad touched the caliper you are done. Remove the C Clamp and old pad a install you new pads.

I cant seem to get the calipar back on the new pads


The new pads are much thicker than your old ones, so you need to get a large C-clamp, like a 5" clamp, open it up, put it over the caliper with the top of the clamp on the back of the caliper and with the screw adjustment of the clamp on the piston of the caliper. Tighten the clamp slowly and evenly, as you may have to move it from side to side of the piston to keep the piston even as it goes back into the caliper. Go back till it is flush with the caliper housing, then you can release the clamp, and the claiper will fit over the new pads. But now remember, you will have to pump the brake pedal several times when finished in order to close the piston back tight to the pads. This can be done with the car running or shut off. The pedal will feel soft and go right to the floor, but after you pump them several times, it will get hard again. Good Luck.

How to change front disc brake pads on 2000 Mazda Bravo B2500


jack up car, remove the road wheels, at the rear of the caliper you will have 2 or 3 bolts holding the caliper onto the stub axle, remove the bolts and remove the caliper, remove the outer pad, leave the inner pad in place and use a "G" clamp to compress the brake piston until it has bottomed, if this is not done the new pads will not fit back over the rotor as the piston is too far out and the new pads are thicker than the old ones.
place the new pads in the caliper and fit over the rotor, replace the 2 or 3 bolts that hold the caliper in place, replace the road wheel, tighten the nuts and lower the car to the ground, pump the brake pedal to see if you have brakes, if you do have brakes take it for a test drive away from any traffic if possible

If it is the rear, please take a good look at the brake pads. One is thicker than the other. You use a thick one and a thin one on each wheel. If you already knew this sorry but I thought ir might help.

How to remove disc brakes for a 2001 hyundai accent


OK..Once you have the wheel off and you are looking at the brakes at the top of the caliper there is a bolt. This one bolt needs to be loosened and then removed. From there the caliper will swing up and off. Have something handy to hold the caliper out of the way so that it does not hang down. I have owned an "02" and an "05" There may be a bottom bolt on your caliper but if it is like the others you can remove the caliper with just the top bolt being removed. Then just take the outer brake pad out and replace it with the new one, and then do the same for the inner brake pad. Making sure that the new pad for the inside does have the sensor. From there using a "C clamp" put one end on the outside of the caliper and the other end on the inside and turn it so that the caliper will withdraw. This needs to be done so that the caliper will fit over the new brake pads which are thicker. Then just slide the caliper back into place, tighten the top bolt and put the wheel back on. Make sure and start the car and pump the brakes a few times so that the caliper will make contact with the new brake pads. From there you should be good to go.

Back brakes kia spectra 2007


Hi bead_crafts5,
My name is Dennis and I hope to be of assistance.
I have to assume that you are trying to get the piston to retract into the caliper while trying to put new pads on a disc brake. When the pads are worn down the piston is nearly out of the cylinder of the caliper and when you try to get the piston to go back into the caliper it can **** slightly in the bore of the caliper. Center a "C" clamp in the piston and carefully screw the clamp closed pushing the piston back into the bore. While this is taking place the brake fluid is being forced back int the master cylinder and the going will be slower than you think it should be. Just be aware that you are trying not **** the short stubby piston in it bore as you force it to retract to allow you to put the thicker pads in place.
Glad to be of assistance. Please rate the solution I can learn from your rating.
Thank you
