My Disc Brake Conversion

Thanks for clarifying that, its a shame because it means i would have to get a set of Wolf rims and my bonnet spare weighs enough as it is!

If you upgrade the front what happens at the rear? If more brake pedal pressure is required to operate the new calipers, does that not increase the chance of locking up the rear brakes?

If you use the Heystee you have Land Rover components so you should select the appropriate master cylinder for a matching disc drum setup from the coil sprung range, you may have to change the rear setup to maintain balance.

Don't know about the Zeus system and I don't know if Zeus have a recommendation for the most appropriate master cylinder, I've read a number of reports about a heavy pedal with disc conversions, probably need to budget for a larger servo as well.

Would be interested to find out what the 6" rims are that Zeus refer to, I don't know of any after market 6" tubeless steel rims for the Series, let alone one that will also clear the calliper.

I know its a personal thing but I really don't like the 6 1/2" Wolf "flywheels" on a Series but I guess it does give you the option of running 235 tyres.

I agree, I like the Zues design in that its all bolt on and leaves the swivels as they are, but the wheel issue is a problem. i was about to order the Zeus kit then stopped because of it. I bought one Wolf "style" wheel and I'm going to take some carefull measurments. I can't see why the Wolk style would clear and the standard wheel would not unless the profile is different. The 6" could only make a differnce if the offset or profile is different too, the rim width alone shouldn't be the issue. Fitting the Zeus kit looks to be about half the work of the Heystee. Re pedal pressure - I've driven quite a few 60s and 70s cars with disc front and drum rear, they are OK, pedal pressure is high but it is on all older cars and its certainly high on a drum braked series even with a servo. Zeus say the brake balance is fine and I suspect that's true. They do say you need a brake regulator if you fit discs on the rear as well. In my case I'd be replacing the TLS fronts with their twin cylinders so there may not be some much differnce in fluid volume. I'm a bit torn on this issue:
- drums are now (at last) working ok, pull up straight, hold adjustment, firm pedal
- but they fade and the pedal pressure is high, we are 2 1/4 tons loaded for camping and a long twisty down hill is very stressful. Lots of use of the gears, very carefull braking. We did a long drive through a very hilly part of Dorset fully loaded and the next day the hub seals were weaping, I'm sure this was heat soak.
- I would like discs on the front but I would also like a disc handbrake and a bigger servo so its about priorities. A better hand brake and a bigger servo may be better value for every day driving. Holding on an up hill on the LWB TLS set up takes a lot of pedal force. Heystee do the bigger servo so that may be my first purchase.

It's the profile.Profile on the wolf is very different. The well, in the centre, is a lot more out board, than the series.

Next time I'm fitting the heystee kit.

Or getting the rims re banded.

Again that pic really helps, thanks
