blagger1 Posted May 13, 2008 Report Posted May 13, 2008 Ok guys, need to replace my rear pads. Have done my front discs & pads six months ago with your help and was just wondering if I can expect any problems? Have noticed that the spring clip in the top of my nearside caliper has disappeared resulting in some play. I get a metallic 'clunk' when I brake (no doubt a result of the aforementioned play. Anyone else had one of these disappear? Quote
seatkid Posted May 13, 2008 Report Posted May 13, 2008 You may have worn the pads to the point that the spring mounting rivet has been ground off. You definitely need a rewind tool (About Quote
blagger1 Posted May 14, 2008 Author Report Posted May 14, 2008 Will a G clamp do instead of a rewind tool? I used one for the front when I did them......... Quote
faz Posted May 14, 2008 Report Posted May 14, 2008 I agree with Seatkid on this, I changed my rear pads about a month ago and think it would have been near on impossible without the rewind tool. Quote
bj2004 Posted May 14, 2008 Report Posted May 14, 2008 A G clamp should do fine as long as its on square and not going to damage anything else you must have the bleed niple open tho to prevent damage good luck Quote
seatkid Posted May 14, 2008 Report Posted May 14, 2008 (edited) You will be very lucky if you manage this. Considerable force is needed to push the piston back while rewinding it at the same time. I tried with pipe pliers etc... and couldn't retract it even 1mm. In addition I damaged the rubber boot on the piston... :wacko: and its just not worth risking writing off the caliper....or wasting a couple of hours.....or a couple of days with the car off the road if you find you cant push them back and have to wait to get a tool (as I did) Edited May 14, 2008 by seatkid Quote

There is a screw section that acts as the self adjuster and it needs winding back in. I used a large G clamp and pipe grips to turn the pad pressure plate. Tighten clamp, about 1/4 turn on grips then retighten clamp, turn again etc. I assume it is the same as my Galaxy. It is best to attach brake bleed kit to the caliper and let the excess fluid drain out. It stops small particles making their way to the ABS and causing problems. This should be done when changing front pads as well. Quote
Shabazmo Posted May 15, 2008 Report Posted May 15, 2008 For what it costs, the time it will save, and you can bet that you will use it again. Buy yourself a rewind tool. Most act as a clamp as well. Its not worth the hassle otherwise. Regards Quote
MAMMYBUS Posted June 17, 2008 Report Posted June 17, 2008 I borrowed the kit from a friend, it took less than a minute to wind in the pistons, an excellent bit of kit, there is a winder available from GSF about Quote
sasquartch Posted May 29, 2010 Report Posted May 29, 2010 Just done this today. I discovered that you really do need the tool. I managed to borrow one from my local garage luckily. Once I had the tool it was a few minutes work to wind the pistons back in I'd definitely recommend anyone to not even bother trying to do the rear pads until they get one. Mine is a 2005 TDI with Lucas brakes possibly other types exist Quote
