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...........

[Dave The Sparky]

Same goes for the rears

[Dave The Sparky]

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

[bgbazz]

That's the same type of set up used on mine Gaz...worked fine.

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

[Bubba]

or llama 4x4 dave is very helpful and there will be no mistakes as your cj is bone stock
