Brake fittings and De Dion axle
I have a problem fitting RD Hydra mech calipers to the GTS De Dion axle.
The calipers were supplied with extended neck banjo fittings but these foul the De Dion tube.
The question is can I cut a slot in the De Dion axle to accomodate the fitting or are there any other fittings that are suitable? At its narrowest
point the clearance is 5mm.

I'm trying to work out how your fitting the caliper have you not got the bearing carrier fitted, the disks are quite a way from the end of the
De Dion tube. link to

Shouldn't there be a caliper mounting bracket and spacer also

Yes, the picture was taken off the car as a mock up to demonstrate the problem.
The calipers fit over the bearing housing with alloy caliper brackets provided in the kit.

Shouldnt there be a spacer between the bracket and caliper as the disk will run a few inches wider than as your pic shows

I'm not sure, there was no spacer with the brake kit. I'll refit the hubs to the axle tomorrow to make sure.
Thanks.

i'd get everything else all built up first, and calipers last. i wouldn't go notching the axle either.
i remember recent threads saying the GTS axle is perhaps not the er, best quality (yours might not be affected, and i don't have one. just
saying what i read) so i wouldn't do that to it
get everything else built up, bearings hubs, discs, etc then see whats what when everything else is on. might not (and if sold as a kit,
shouldn't) be a problem.
i'd be very surprised if any manufacturer sells a kit which just doesn't have a hope of working

Brake fittings and De Dion axle
I've fitted the hub, disc and caliper and it seems to fit fine, apart from the gap between the caliper and De Dion axle.
I think I need to find either a suitable replacement for the banjo fitting or cut a small slot in the tube to clear it.
Any ideas?

I take it that swapping the calipers to the opposite side of the car and inverting them, does not improve the clearance problem??
It might cause your handbrake cable to run at a funny angle, but that would be safer.

Have tried inverting them and swapping sides. They are still too close to the large tube on the axle.

I'm trying to look at the photo but am struggling to see but is it possible that you could remove the springs and put them in the other way
about so they stick away from the axle as oppose to sticking into it? Just a thought.

Thanks, the springs and handbrake mechanism are clear of obstruction and will work OK. The problem is the fluid connector entry which is underneath
the caliper. At best there is 5mm clearance between the port and the large tube of the De Dion axle. The caliper is supplied with a banjo fitting
which is 20mm deep.

VW callipers mount in the same way but the inlet is in a different place. I think the Hydro mechs are a bit lame, there is a conversion for a
Westfield with the same problem. The two options offered were: 1 use VW/Audi Callipers or 2 re-drill a new inlet on the hydro mechs (not ideal).

Hi, Is that a hydra mech caliper thats been re-drilled, if so how easy is that to do?
If I cut a slot in the axle as per the picture below, will it weaken the axle that much?
