What is the best way to push the brake piston back to install new pads? Im use to pulling the whole caliper and using a caliper press tool.

Re: Brake Piston (thorne)

I don't think there is any need to push the piston. The Brembo brakes have two pins and a spring holding the pads in. Remove the spring and the pads slide in and out. Do a search for more detailed info.

You need to push the the piston since the new pads are going to be thicker than the worn pads. I just used a screwdriver handle, doesn't take too much force to push the piston back.

thanks, i didnt know what it would take to push it back in place. I always remove the fill cap to relieve pressure. I would just hate to remove the caliper if i didnt need to. thats a b*tch

Wedge a flathead screwdriver in between the rotor and pad, then, using the edge of the rotor (outer edge) for leverage, pull on handle of screwdriver so that the screwdriver acts as a lever and pushes the pad in, thereby pushing both pistons in. Do that for each pad in each caliper. Easy as pie and no damage to the face of the rotor, since the point of contact for the lever (screwdriver) is only at the edge of the rotor. If you want to be extra cautious, you can stick a piece of wood or a rag in between the screwdriver and rotor, but if you are careful and do it slowly, there is no need, you won't even scratch it or dent it.<p>Tip: before wedging the screwdriver in between pad and rotor (which could scratch the rotor if not careful), use the flat head end and push in on the pad's backing. This will push the pad and both pistons in a bit, enough for you to get the screwdriver in there and use it as a lever. Once you do that, it's very easy to completely push the pad all the way in.
