rear brake rotor machining - can it be done on the Disco?

Unread post by 4x4Coaster » August 23rd, 2013, 6:42 pm

G'day all,
the wife's car is a '97 discovery and I just noticed the rear brake pads are a bit low and the rotors could do with a skim.
Then I looked closer and it appears you have to remove the axles , hubs and bearings just to get the rotors off!

Am I wrong?

do some machine shops just machine them on the vehicle? I have heard of this being done on other vehicles.

any advise?

In the end I just decided to do it myself, so today pulled it all apart and then found the wheel bearings had bad wear spots on the cones and some pitting. After dropping off the rotors for machining, I went & got 2 sets of bearings & inner seals.
I also decided to change the diff oil while I had it all apart. It's all back together now & I'm glad I did it, parts alone cost 175 for bearings & seals, 70 for pads & machining, 20 for diff oil & I had to buy a 2 1/16th socket & 3/4 to 1/2 adaptor so I could tension the nuts on the spline, socket & adaptor cost 70.

I also read on someone else's thread, can't remember who's, about using the old cones to knock the new ones in, cut a slot with a grinder in the old cone and its easy to remove, I have to say it works brilliantly!

I reckon I probably just saved about 600 to 700 by doing it myself if you include the markup on parts & labour.

Now the rear end is all good!

In answer to your original question - yes, it can be done on the vehicle by specialists who have the right gear.

But what you have done is a far better outcome in every possible way, without even considering the money that you've saved. I've never been a fan of machining discs on the vehicle for exactly the reasons that you've found - if you had not removed the discs, there are so many other things that you might not have even looked at. :drink:
