I bumped into an unexpected pain in the butt type of problem today. I was replacing the brake pads on my GQ(1990, single piston) front end. All went nicely on the left hand side and it’s was all over less than ten minutes.
All I had to do was to undo one bolt and lift the calliper top assembly. Then press the piston with a clamp and slide in the new pads, lower the calliper top assembly again. The two bolts that hold the calliper top assembly moved freely without any dramas for me to push it back in again.
Right hand side is another story. After two hours still I can’t get the calliper top thing to go in.
The reason is that the bottom bolt is stuck like it’s welded to the calliper body. I can turn it both ways with a spanner, but no chance pushing it in or taking it out. The top bolt is fine, it comes out easily and goes in the same way.
What can I do to get it to move guys?! Hitting on it with a mallet or hammer didn’t work. It won’t move at all, but it turns, though without moving in or out.
I took a photo, but can’t post it as I can’t find the USB cable to transfer the photo to the computer.
I will post the photo tomorrow.
I tried my best to describe it, but I know a photo could’ve saved me thousand words.
I have no idea why it’s stuck like that. I had to put the old worn out pads back in. Since they are pretty flat worn, calliper top not moving in(and out)doesn’t affect the ability to lower the calliper top.
I’m also beginning to suspect this is probably the reason I feel the brakes aren’t good enough to hard stop the GQ when I need to do that. I feel brake’s bit too weak, but I know it’s a heavy car and I got disc brakes on both front and back.
Any help would be great.
Thanks guys
