Anybody come across this?
I think it was on wheeler dealers a couple of years ago but I have not come across it since.
Basically the disks / pads on my 79 CJ7 were pretty much new when it was parked up 20 years ago, but are now more than a little scabby...
-
I've had this done a few times and I'm pretty sure that if the end result meets the legal specs for disc thickness, you will be fine.
Obviously, new pads will be required.
-
Flappy disc pads first
-
Is it not easier just to buy some new discs from Rock or Lightys first then you know they are right??
And whilst you are at it buy a caliper re-seal kit or 2 new calipers because Jeep brakes seem to seize up after 5 minutes of inactivity never mind 20 years the chances of them being okay are very low...........
-
Same goes for the rears :003:
-
And the mastercylinder too, they aren't stupidly expensive and is it really worth risking?
-
When I first bought an XJ moons ago, the front discs were warped so the seller replaced them with new discs & pads but they still weren't running true.
Local Jeep Dealer (when they used to be about) had it & trued up the discs while still on the car so that they were true to the hub. They had a purpose built grinder set up on a trolley / bench affair, problem solved :)
-
That's the same type of set up used on mine Gaz...worked fine. :greggmo:
-
if they are warped then replace with new, regrinding can be a pain if the clamping surface is not true
if its taking the lip off the outer edge then grind away with the trusty grinder
-
Looks like I am buying new discs, pads and calipers.
Or, is there an upgrade available to a more modern / better design?
That would make a worthwhile amount of difference in "normal" on road / greenlane use?
For a reasonable amount of money? - Lightys want £335 for the above. (I know I can get it cheaper from elsewhere, but I like their call handling, technical support and the fact that everything always seems to fit when it arrives...)

wilwood do an loverly upgrade but it comes at a price (£800), plus you need to change the rim size to 16" as the calipers dont fit inside the standard rims
-
i think given where you are with things lightys is your best if not cheapest option
-
or llama 4x4 dave is very helpful and there will be no mistakes as your cj is bone stock
