Has anyone come across a mechanical handbrake only caliper?
A mate of mine has just been through the test with a Jag based kit car running a separate hydraulic handbrake system. Failed!

Any ideas guys?

RD advertise a Wilwood MC4 mechanical park brake caliper in the catalogue.
Not sure how effective it would be though.

If your mate is feeling flush, new aston v8 vantage h/b calipers are about £210 each, and pads are £25 a set.
I've got one to mot tomorrow, i'll post up the h/b efforts for comparison.

I'm fitting MC4 calipers, they seem a nice piece of kit, with sliding mounts etc as part of the unit. £80 plus vat each. They are more effective than the wilwood spot handbrake calipers which by rally designs own admission aren't that effective.

The aston ones were 188 and 203 kgf - enough to pull the vehicle out the rollers with 23% efficiency and more effort available at the lever.
The only difference visible mechanism wise that i could see is the handbrake lever is about 1/3 longer than most cars.
That mc4 look more suitable than the older spot caliper, the old spot caliper struggles to pass mot on a quad based pickup let alone a jag based kit.

Dont think he can run to Aston calipers!

By the way the rear brake discs are 25mm thick! So that creates a problem!

hi spec do these rear caliper's, which are a combo hydraulic and separate mechanical hand brake mechanism, and also a mechanical only style.

they are IVA compliant and can be specced in different widths.

does that help?

I saw these at stoneleigh £100 a pair kinda wished I'd picked them up now
