Title: zj- brakes part rwo
Post by: mean dog on July 04, 2009, 08:45:13 PM
Many thanks Tank & Daggie,
  Stripped brakes down again, pistons and sliders seem to be working ok, put old pads back on, no problems.It seems to me that the new pads are to thick!!!
Does anyone know the thickness of genuine Jeep pads? The new ones are just a fraction under 3/8 of an inch, dont know how much was rubbed off after doing about 50 miles. Got to get this sorted, going over the Alps end of month, and her indoors is flapping a bit, 'Im not going in that, get it sorted' mmmm now thats a thought Ill go on me own!!
Thanks :    :icon_rolleyes:

Still could be the calipers.I cant imagine the pads being too thick if bought correctly.If you can get everything back together with new ones in then i cant see that being the case anyway

Check the guides on the steering knuckle that the brake pads slide on. These are often notched where the brake pad has been rubbing over the years and it could be that the pads are sitting stuck in the dimple rather than freeing off after use. If this is the case just get someone to fill the hollow with a welder then grind it all flat again. I have done this a few times and it works great (even though I know in theory you shouldn't be able to throw weld at a cast peice?).

Thanks again guys,
Will check out  the info. that you gave me, Tank, as you said the new ones fitted with no probs. Strang though, no probs. at all with old ones.
Let you know when I've sorted it.
Thanks again

I've had my zg for over 3yrs & this was the 1st time i've changed the pads & discs :icon_rolleyes:
I think it has summat to do with the piston being so far out of the cylinder, for so long, the it gets pushed back in it won't budge then gets stuck.
and the rubber sliders just wouldn't slide, no matter how much lube I put in them

??? :102:

good luck
