Thread: Disc Brakes

This picture is the hub adaptor and the original 101 landrover hub without the disc and the old Loctite being tapped/cleaned out of the threads.


I use AJ for the hub oil seals as he supplies the original landrover ones which have a extra dust lip and are better than ones purchased from a bearing supplier.
AJ can still supply hub gaskets and hub nut locking plates.

I had a quick look at fitting the Zeus disc kit I have too the rear of my 101 Landrover.
To do this I will have to make some new brake lines for the rear diff as the old ones will not line up for the disc calipers.( Zeus kits are designed for the front axle)
This will be no problem for me as I fabricate brake lines all the time at work and have the gear to double flare and bend the pipe ect.
I am not rushing into this as I have too many other things to fix on other vehicles I have and the rear drums are working well , especially with the discs fitted on the front.
So much so I am wondering if fitting them on the rear is going to improve any thing and the rear brakes wear little on the 101 as the fronts seem to do most of the work.
Zeus are definitely working on a better design of disc brake for the 101 Landrover .
If they go to a single piece design of hub adaptor and disc it will allow a much needed weight saving and get rid of the allen head disc bolts which gave me trouble.
Their discs don't seem to wear so if you replace the pads when you are suppose too, the single piece adaptor and disc should not be a problem.
The other way to improve the set up would be to leave it much like it is with separate disc, but to use Six allen head bolts to hold the disc and the threaded bolt holes line up with the wheel stud holes.
that would allow large slots/ holes drilled into the adaptor to lighten it and improve cooling.
Drilling of the disc rotor would help cooling too.
It will be interesting to see what they come up with and they seem to want to keep in touch
Zeus have come to the party and reduced the price of the replacement disc rotors when they could have toll me to go to hell.
I am thankful someone went to the trouble to design something to a limited market and are happy to sell it as the disc brake design on the 101 landrover is very tight and not easy.
I do know I will never go back to the drums on the front my 101 landrover.

PS if you are interested at current exchange rates 101 Landrover front axle Disc brake kits works out to be about $1800 dollars landed from Zeus and in the scheme of things if you were to make/ adapt something here is still good value if you account for your time and mucking around.
Our dollar is currently slowly improving so that figure could improve.

Are the bolt holes in the discs (still?) angle countersunk?

DL

They are not angle counter sunk, but sit on a flat face.
They were extremely tight, enough to cause stress near the inner edge of the disk and to spread the holes that way.

Just to up date a old thread.
I have had word of another101 Landrover owner with Zeus brakes fitted front and rear with cracked discs exactly the same way mine did and on more than one rotor.
My problem is not unique.
101 landrover owners check your disc brake rotors for cracks regularly.
If you are running these type of brakes I would suggest making a effort to reduce the torque on the disc rotor bolts to reduce the chances of the rotor cracking.

Hi Ron,

I've got the same issue... I have been told that my Zues brakes are also cracking - something I plan to investigate this weekend when I get a chance..

Cheers,
GG.

Post some pics if you can.
Should get as much evidence as possible and see if Zeus want to change the design or back off the torque on assembly of the disc rotor bolts and see if they are willing to do a deal on replacement rotors.
giving the evidence back to Zeus should help them see they have a problem.......and a possible dangerous one.

The Aussie conversion kit in the works shouldn't have a cracking problem ,or parts replacement as it uses mostly off the shelf landrover components.

Yeah, I'll be buying one of those Aussie conversions as soon as they are ready.
