Outer Limits 4x4 Board

I been thinking guys I know its tough. I hear about the pro and cons of rear discs and rear drum brakes. I have RDrB on my 60 but hear discs are so much better. What would be involved to change from RDrB to RDiB? Is it worth doing?Thanks guys. joel

This interests me too. My 60 has drum rears and every time I go through a decent mud puddle, they fill up with crud and the pedal goes spongy. IIRC, you need fully floating axles for disc brakes, which you probably don't have. Since I've fitted Toyota locker diffs, my rear is fully floating, so maybe a disc conversion would be feasible...

This wouldn't happen if you didn't go from being stuck in one hole to being stuck in another 30 seconds after being recoverd from the first!

Yeah, thanks Jusso

why do you need full floating axles?

i thaught most australian model 60's are full floaters anyway, mine is(89)

you can get conversion kits from the states that use chevy calipers

or you could do a search and find one of the 10+ threads that has discussed this already. Essentially youy use the disc off the front of a hilux, the wheel studs from the front of a 60, the caliper from a subaru (which have handbrake level integrated), then make up a customm mount for the caliper. Then use an 80 series master cylinder....

Can someone explain full floating/ semi floating axles?

Full floating refers to how the axle is held within the diff housing.

A full floating diff housing is very similar to a front solid diff, without the swivels joint/CV's. IE there is a hub which mounts on a bearing & has the brakes attached to it. The axle then plugs into the centre & onto a drive plate at the outer end.

A semi floater has the axle & bearing as one & the brakes attach to the ends of the axle.

Basically, if you remove the axle from the rear of a full floater the hube etc stays on & you can continue to drive. If you pull the axle out of a semi floater, the brakes etc go with it & you are stuck until you fix it.

Putting a ARB locker DOES NOT covert your rear to a full floater.

60's do have full floating rears with drum brakes.

GQ's have semi floating rears with disc brakes. It is not a requirement to have a full floater to have rear disc brakes.

Full floaters are stronger as the axle only takes torsional load (ie twisting) and the vehicle weight is carried by the hub & therefore the housing. Semi floaters the axle takes both torsional & radial loads.

That'd be a "dana" 60 rear diff, not a "60 series" diff.

that it is

Why not use 80 series ones?
