Rear disk brake conversion disks?

[DaveT]

Are these the correct disks for converting a 4WD EA82 wagon to disk brakes?

Thank you,

Yeah, but you'll need the hubs, backing plates, calipers and brackets off an XT or ea82t car.

I just figured, I might as well get the new rotors - no doubt the scrounged ones will be half used or worse.

 

Thanks again,

Actually may not be but good chance they are. The XT FWD turbo model eg came with 4WD. I've been told rear discs between the FWD and AWD models do not interchange.

Hmm,

 

Well, they only let me order 1, so either they are out, or have silly quantity rules. I'll probaly have it next week.

Yeah, the donor car must be 4wd. And I think non turbo 2wd XT's were still rear drum brakes, at least the subie literature I have says they are.

any turbo EA82 has rear discs.

 

hubs and backing plates are different between FWD and 4WD.

 

you can bolt FWD rotors to 4WD hubs (although you wouldn't otherwise have to seperate them....)

Actually the rear rotors are usually in good shape - sacrificial pads, and the minimal 30% braking done by rears in general makes them generally wear for a very long time.

 

The backing plates are often rusted to peices and near impossible to get off though.

Only difference between the two is the backing plate; otherwise they are the same.

Of all the rear disk conversions I've done and pulled, I've never had to replace the rotors. Only once did I have to have them turned. I couldn't find the rotor you were looking at, but worst case is that you would need to have the old rotors turned before installing them. Just for a price point, conversion kits for rear disks normally sell on the USMB for $100 or less plus shipping (that includes all the used parts you'll need). And yes, FWD kits and 4WD kits would be different (the backing plate is the primary difference).

GD is right on with both opinions. Backing plates sometimes require huge amount of rust penetrant, a good sledge hammer (only beat on the re-inforced portion), time, and patience to remove. I've never found a backing plate I couldn't get off; but I have spent as much as two hours on the worst case samples. It helps to scrape the built up rust off the hub with a pen knife before trying to remove the backing plate.
