DOHCRagtopguy Posted July 25, 2007 Report Share Posted July 25, 2007 Do yourself a favor and buy 2 loaded rear calipers (calipers w/pads attached). Turning back that piston can be a royal bitch on these cars with or without the tool. Sometimes the piston must be pushed in and turned at the same time in order to retract fully. I've had enough bullshit with that, so now I buy loaded calipers for the rear on my W-body. Quote Link to comment Share on other sites More sharing options...
xtremerevolution Posted July 25, 2007 Report Share Posted July 25, 2007 I've always used a c-clamp. Worked every time, and brakes just fine afterward. I've changed the rear brakes 4 times now since I bought the car. Quote Link to comment Share on other sites More sharing options...
GP1138 Posted July 30, 2007 Report Share Posted July 30, 2007 I used this really cool tool at work when I last did rear brakes. It consists of two metal shims, with a threaded insert that turns the piston while keeping pressure on the two shims, that go between the caliper and the piston. The threaded part has a 1/2" head at the end you turn with a wrench. Easiest rear pad job I've ever done. I think it was special ordered though, but I'd ask about it at AutoZone or Advance.

jeremy Posted July 30, 2007 Report Share Posted July 30, 2007 the rear brakes are pretty easy, but I've always used a special tool like John mentioned Quote Link to comment Share on other sites More sharing options...
badassoldspower Posted July 30, 2007 Report Share Posted July 30, 2007 I've always used a c-clamp. Worked every time, and brakes just fine afterward. I've changed the rear brakes 4 times now since I bought the car. That doesnt work on the rear calipers, being as they are an integral parking brake style caliper, there is a threaded shaft behind the piston, you cannot simplly push them back, people have tried using a vise to compress them that way, which ruins them.

GutlessSupreme Posted July 30, 2007 Report Share Posted July 30, 2007 stick a small block of wood between the piston and the c-clamp. the block will squish to fit the slots on the piston and will twist it. Quote Link to comment Share on other sites More sharing options...

GnatGoSplat Posted July 31, 2007 Report Share Posted July 31, 2007 I got this on sale from Harbor Freight when it was $10. It can rotate while pushing in at the same time. Well worth it when it goes on sale. http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=40732 Quote Link to comment Share on other sites More sharing options...
