I think we overcooked the handbrake!

Post by AndyPen »

Back in the day we used to reinforce the floor behind the handbrake with those plates off the front subframes of later cars. Stiffening it up gave greater leverage for hand brake turns. We actually cracked the tunnel on the 1071 behind the handbrake in the end!

One day the SDL 970 front handbrake mounting simply snapped off, and to this day is still held in place by a bodged in light holder that we bolted in 'temporarily'! The hole for the diamond type bulb holder was the perfect size ;-)

A reminder of that event, plus a realisation the holes we welded up had been for reinforcement (and should have been left alone), led me to check the 1071... and ouch, we have a crack to weld up!! Luckily Bryan Purves has recreated the reinforcement bracket too, so another little job to sort whilst social distancing ;-)

Didn't expect a handbrake to overcook, but I am sure any of you mini drivers of yesteryears recognise the issue?

That's a good heads up Andy. In my experience that area is somewhere that is rarely intact & can usually do with a bit of beefing up. I have had a couple of cars where the weld at the front, where it joins to the crossmember breaks. It always looks a bugger when it has been welded up after.

Also worth looking to see if the floor Cross Member is also distorted from a big yump.. remember the works put in a double cross member.. a second one welded over the standard floor crossmember so it was not easy seen by the authorities. ;)

This was a common problem with all minis back in the 70's, the weld to the crossmember would crack and then the spotwelds to the tunnel would fail soon afterwards.
I 'double skinned' mine so I have two flanges to the tunnel.

That car of yours certainly is going to be something special Bob!! On this car the spot welds didn't fail, but the metal behind the bracket fatigued and split, hence the rough and ready use of of the front subframe brackets - which I've kept as a part of the car's history.

It was only when I saw this reinforcement on Bryan's website that I realised what the other holes below the front of the bracket had been there for... grrrrr.

Here you go. As far as I can see it matches the ones originally on our cars, or so close I can't recall a difference ;-)

Do you need to drill any holes? or it's plug &play??

Yes you need to drill two holes in the tunnel - the ones we welded up I guess !!!
