ok, on the front of the pickup, i've got standard bedford midi brake discs and standard calipers (similar to sierra, with the 1 piston) good enough for stopping a van, should be fine for the truck

thinking of using cortina calipers (M16?) on the back and willwood spot calipers for the handbrake

what do you think?

edited to say, i've not actually bought anything yet, just thinking. I've already got the cortina calipers which i can't use up front, and i was given the bedford calipers, but would prefer willwood brakes all round

How heavy is your truck going to be?

Bedford Midi's are pretty lightweight. Certainly lighter than the Cortina...

I'd worry you'ld have good brakes and the back and not much up front....

I'm not sure the Wilwood spot caliper is going to be good enough for road use. To quote the Rally Design catalogue:
"...prevents motion of the vehicle on show cars - handbrake has limited efficiency"

the trucks only about 850kg.

yeah, i'd worried about that too,
i was thinking though, if i set all the brake bias to the front it should be ok? maybe? hopefully?

I wonder have you ever tried cortina brakes?

Even new they were crap

lol, i had a cortina for all of 3 months...

I have a willwood spot for the handbrake on mine - on a 8" diam disc on the prop. It is surprisingly effective - 2 fingers to pull up. I would not like to use it to stop the car from speed - it is too effective & would be difficult to modulate.
When I asked the same question a couple of years ago, the only other user to reply had put one on his range rover!!!!

That sounds fine, but I would say the rear is ott in terms of complication.

I'd just use either std sierra rear handbrake calipers for both service and handbrake, or scorpio cossie rears if the sierra ones were too small, or use the ally golf ones that fit ford mounts, they are only 40-odd quid new from rally design and are plenty big enough.

Depending on how heavy the rear is going to be you have a choice of Rover 400, Golf, Sierra or if you want bigger Rover 600 calipers -- you will need some means of controlling the brake bias.

If you have a Ford wheel PCD go for Escort Mk3 1300 discs (same as early Sierra)

Cortina calipers are far to big and powerful to use on the rear.

We used rover ones on the back of a gravel stage rally car, i..ee with 50/50 brake bias, deffo too much for rear of a tarmac car unless its super heavy

"Transmision brakes are not a good idea -- nasty things that why the fell out of use i the 1920s except for Willys Jeep & Land-Rover. "

Actually the transmission brake made a lot of sense when I was working out my brakes;hydraulic only rear service brake with no cable routeing issues or supply issues. The only problem with it is that it's TOO effective, it would be risky to use it from speed. As a parking brake it performs just fine. Downsides are 1) you can hear the pads move while you drive (it's quite close) and 2) there's some relilience and backlash through all the CV joints & driveshafts - probably an inch or so of car movement. Not an issue at all at SVA or MOT. Unsprung weight IS important & this is a potential route to reducing it.
