Brake piston/rewind tool

**123rado** · 25th December 2012, 16:44

Merry xmas guys. Hope someone can help.

I set out to quickly change my rear brake pads this afternoon as I could hear a sort of rubbing noise of metal from the rear of the car.

Changed the offside one with no problem but after putting on new pads on the nearside (pads were already low and piston probably fully out) and winding in the piston, the rewinding tool is not coming off when I tried to take it off. Tried as much as I could but to my surprise the lever on the rewinding tool that is used for turning is bending.

Anyone know why it is not coming off?

Screw/unscrew the part with the nut on it (right hand side of picture)

easy peasy

If the threaded rod is bent you will have trouble removing it without damaging it. From the look of your piston its not fully retracted, shouldn't the piston be hidden by the rubber at a side view like your photo.

Your suggestion makes absolute sense as both the nut side or the threaded side are movable (in opposite direction to each other). Will try this first thing tomorrow and hope it works. Thanks.

It is not the threaded rod that is bent. It is the lever handle that is used for turning the tool that is bent. Although the piston might look not fully retracted, I tried placing the calliper in position and there is enough space for it to fit in when the rewind tool is removed. Thanks for the reply.

As said above....

You need to wind the larger nut in to release it.

Try turning the handle as if you were still winding the piston in and turn the large hex bit the other way.

Thanks mate. It all sounds and looks straight forward now. Just did not think of that because I have never had to resort to turning the hex bit. Will complete the job in the morning when there is light.
