Mini handbrake setup
Turbo Mini Forums

I have perfectly good rear brakes on the mini but unfortunately with the car being a racer, no handbrake.

I want to retro-fit a handbrake to it.

Its currently short of quadrants, cable, lever etc but also the bits inside the rear drum/backplate.

What i'm trying to now figure out is exactly how it goes together and if any bits have been ground off the backplates etc.

Any photos etc would be great of a built up rear drum.

Its going to be fun putting it back together with one, i'm guessing i'll be missing the centre bit that turns them through 90degrees before going to the quadrants as well.

I've never really took a lot of notice of handbrakes until not having one!

Cheers
Iain

Ps if anyone is cutting up a car with the handbrake brackets or has any old backplate bits that would be great!

Even better if someone wants to fit me up a handbrake for a few pennies thats good too, although i dont want to travel far. I'll try to get it done myself but short on time!

You could bolt a set of old qaudrants on instead of refitting the old style runner ones. This would prbably aid the handbrake imo.

yeah i was thinking along the lines of making the inner ones move, was thinking of just using some sealed bearings for them to run on.

Looking at it i need the lever bit inside the back plate, the bit that splits 1 cable into 2, hand brake quadrants.

Does the handbrake and quadrants run along the top or bottom of the radius arm? and is it a subframe off job to put this little lot in?

Plus a cable and a lever. Easy

The yoke, lever bracket AND adjuster nuts do NOT come with cables.

Wil_h's list is otherwise comprehensive - just make sure you don't get the twin cable type lever!

cheers for the effort. mucho appreciated!

I'll get the bits sorted, some of which i have mind.

i just wasnt so sure on the brake internals.

It will be on the road eventually...

Also:

You can't fit the quadrants with radius arms on. and they are on the bottom side of the radius arm.

I'm also unsure about the cable locating brackets on the back plates, left and right hand ones. These might still be attached to your car though.

Here is the full list then, soon adds up! + VAT and postage as well.

Have to see if i can find a few of the bits. I've spotted some of the levers on ebay so fingers crossed!!

Thought the radius arms had to come off. balls.

The guide for the cable is in the bottom of the subby isnt it? hopefully means i wont have to resort to taking the subby off as well. next problem is most likely the fact my exhaust will be in the way!

Wil, just clicked what those guides are and i dont have those either. arse! more expense.

I have spare long clevis pins (go through the radius arms), quadrants(not KAD ones as I just put these on my car) and a brand new front section of the hand brake cable if you want them?

i managed to fit the quadrants after putting the radius arms on - i forgot - you just need nimble fingers and lots of patience

Nice to know,

i'll give it a go without taking them off first then.

wahts the law on hydraulic handbrakes now ? could you get away with a cylinder in the rear line operated by the handbrake lever at all iain ?

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

For an MOT you need a mechanical brake .... otherwise a line lock to the rear would be good enough.

Every day is a school day ...........

How fast and how expensive ...... the same question...

ah thanks roger , i thought they had changed it ,thats a shame .

No you dont Roger

If its pre-68 you can have a hydraulic handbrake.

I had thought about one but it would be a fair bit of mucking about as well to be honest.

Ordering all the bits tomorrow

OK Iain, your correct about that. Thought that as your car is an ex-racer it wouldn't have an identity to use and thus you'd be registering it from scratch as 'rebuild' or similar and going for an age related plate to go with a "donor" car docs you had.

If you have it on an early ID then just slot a line lock in ..... far quicker and easier than faffing about with a mech hand brake on your car! Not like your going to leave it parked on a hill in the high street is it .. lol

You see mine was built with a brand new heritage shell from a early donor so kept its id's with it

its a 69 though.

well thats all those bits ordered, thought i may as well go for new stuff as its done and dusted then.

Had a chat with rich at minispares north and fingers crossed i can get it done at the weekend.
