custom drum brake
coyoteboy - 1/8/13 at 09:13 AM

Has anyone considered mounting a drum brake for the handbrake on their custom build? I'd like a 4 pot rear caliper but the options with handbrake capability in there are limited for those using custom uprights.

Thoughts?

Land rover?

How about a combined drum/disc?

Old LandRovers have a drum on the back of the gear box,... perhaps one could have a custom handbrake on the propshaft,.. diff flange or similar, leaving the discs on the rear to be what ever you want,....

Any possibility of mounting a spot caliper on the upright in addition to the 4pot?

Here is an off the wall solution, fit 2 single pot rear calipers per side --- you only need a handbrake on one.

Rolls-Royce did this for years on the front from the Silver Shadow onwards.

I hate transmission brakes they can be really quite nasty if you ever have to use them to stop a car but they do make very effective parking brakes.
A bit of very ancient history --
When rod operated front wheel brakes very first introduced in the 1920s many manufacturers used a transmission brake coupled to the foot brake as the main service brake. Willys used a transmission handbrake on the original Jeep models so Land-Rover copied it but used a drum brake rather than contracting band.

I've considered a spot caliper but they're almost as big and heavy and the main caliper and I've read a lot of reports from people saying they're only bearly capable of passing IVA/MOT, as with the wilwood type IVA capable 4 pot.

BT - two calipers? The handbrake needs to be mechanical only? Are you thinking one mech, one hydro?

Loggy - that was my idea, yes - combine the two (same as on the rear of my Celica) - works a treat but the complexity of the drum put me off a bit and I wondered if anyone had done it before with any success.

No two hydraulic one a golf alloy rear to give you a mechanical hanbrake.

Rolls used 2 Lockheed callipers similar to those found on an MGB or early Transit on each front disc.

Twice the mass, but I see where you're going. Also most OEM calipers are steel or based on steel caliper holders which is a bit heavy for my liking - this could be tweaked though!
