Handbrake issues
Hi all,
I am still planning my saab 96 v6 project. Have been looking at fitting the mondeo suspension in the back of the car, mounting the subframe underneath
along with the struts in the wheel arches. This does increase the rear track by about 30cm which i am hoping to sort out with wider arches and thinner
tyres.
However my main question is now that i am throwing away my rear axle and fitting front running gear, what do i use for a handbrake? i can't use
a hydraulic one for road use can i?
any ideas would be gratefully recieved

There must be a road legal way to use a hydraulic HB as jaguar use them
How long can i resist the temptation to drop a V8 in?

track can be addressed by using wheels with a large positve offset.
can't work out what it is sexactly you are doing due to lack of info. but are you putting engine in the back?
if you are putting monea rear end in the bakc, then surely mondeos had handbrake on the rear?
options to consider are:
1. transmission brake on acting on the prop, like on Land rovers
2. fitting another pair of cable operate calipers onto the discs.
3, carry a set of bricks to chock up the wheels.

that would be easiest but i am fairly sure i have read on here that you can't just use a hydraulic handbrake for the road. I;m assuming its
because i would be using the same lines and calipers as for the foot brake and you need another separate system. Jags prob have a separate system.
Though i could be talking complete rubbish here, hopefully i am.

Sorry i didn't say fully, its basically going to the whole engine and running gear from a mondeo v6 into the back of a saab 96

Most aftermarket caliper suppliers like wilwood have handbrake adaptions or spot calipers that are cable operated. If you aren't using the
Mondeo calipers then just make sure you use either another car's back calipers or suitable aftermarket type.
You are correct Construction and use regs require a separate handbrake system totally independent of the main braking system so your existing
won't get through SVA or MOT

I thought it had to be a mechanical system for the handbrake?
Could you use the Saab 900 front callipers on the back as they have the handbrake annoyingly on the front axle.

aren't all mondeos front wheel drive?
i'm not sure if what i've said is relevant because i don't really understand what you're doing. but you have a saab engine and
gearbox and you want to use the mondeo rear end? is this a front engine front wheel drive car?

He's making the car rear engined, hence if he used the Mondeo uprights he has no handbrake at all.

A 30cm increase in track is going to be difficult to compensate for by changing offset IMHO

If he's just putting the mondy power unit in the back of a saab and the handbrake is already on the saabs front wheels, what's the issue?
why can't he just leave the handbrake alone, acting on the front wheels?

He's doing a saab 96, not the 900. The 96 had a rear handbrake.

As far as I am aware a hydraulic handbrake is legal. It must be completely separate from the service brake though.
Has no-one got away with what was used on rally cars a lot? That is an in line mastercylinder (hidden) operated by the handbrake lever and a pair of
cables (for show) also operated by the handbrake lever and then routed through two opposing holes in the pad backplates.
Our cars got through MOTs with this system in 85-87.

It needs to be mechanical, but may have a hydraulic 'assist' which is how your system got through MOT. Not sure the SVA men would be
quite as keen though.

Our system got through MOT (and scrutineering) because the tester did not know that it was a hydraulic system.
All he saw were the cables and of course on the rollers the handbrake worked amazingly well!!

actually thinking about it going with saab 900 calipers on the front will be easiest, as will have to modify the front hubs as saab 96's have a
PCD of 5x170, which is almost unique so will not be able to match wheels to the mondeo hubs at the back. you can fit saab 900 hubs on the front tho so
may as well use the calipers too along with the handbrake associated with that. I think the ford PCD is the same as the 900. Will have to check.
