replacing rear brake pads alfetta gtv

[greengtv8]

With the pads...adjust till the wheel locks up, then back off till just spins freely, usually back off about 1/4 turn...ish. In general, pads do touch the disc constantly, but shouldn't have any pressure on them. It is something that takes time/practice to get them just right.
      Rebuilding calipers is simple enough...lay the parts out as you pull it apart, don't lose anything, like the little circlips! take photo's as you pull it apart if your really not sure. When putting together dip the seals in brake fliud to wet them. This lubricates them and lets you slide the bits together nicely. Use the adjusters to push the pistons out and if it goes together correctly, the adjusters should pull them back in too. Don't forget to remove and clean the bleed nipples aswell. Calipers usually leak around the adjusters, especially when adjusting your pads, but if your doing a full rebuild, this should all be fixed. If you clean everything and dry it all, but then plan to leave while waiting for parts, etc, wipe pistons, the bores, and around the adjusters with brake fluid, this stops it all rusting up. If honing the bores, use brake fluid as your lubricant. Also don't wire buff the outside of the calipers, look nice and new when it all goes back in the car, but in a few months, the weather will get to them and they'll start to look very 2nd hand.
       There pretty simple but yell if you need more info...have fun!!!

I might give the adjustment another go.from what your saying i think that maybe mine could be a bit tighter.
Good tip about the bleed nipples,they seem to collect alot of road grime in them.
I recently replaced the rear brake line. when i went to bleed it up three out of the four where ckocked up with gunk.

If you really want practice you can come and help me put my calipers back on next week    It's easy replacing the pads when the calipers are on the bench!

It's not too bad a job getting the calipers off, I just made sure I got lots of advice first, and was very careful not to strip any bolts.  Took about 3 hours to get both sides off.

I left the rebuilding of the calipers to an expert though, that's one thing I couldn't afford to get wrong, plus i don't want to have to do the job again in 3 months!
