I've disconnected the front-to-rear brake pipe that goes through the hydraulic handbrake and put a reservoir on instead. This will allow the handbrake and footbrake to be used independently of each other. The pipe will stay in place for the day we go hillclimbing or decide to get an MoT.

And it depends on the club what the class structure is. My own club I'm in the Kits/Specials class, so I'm playing with chopped down Minis, etc. The other local club divides classes by drivetrain and engine size, so I'm >1601cc RWD and in with MX5s, who are under 1600cc but move up a class as they're 16V.
Shouldn't be strictly necessary Steve - if you're competing under an MSA permit, then you're covered by MSA insurance. This is where part of your entry fee will go. I was Clerk of the Course at an Autotest where there was an accident - a car got out of control and hit a parked truck. Driver wasn't hurt but there was a bit of damage to pay for. We informed the MSA who dealt with the claim from there, although the organising club was liable for £250 excess.

MSA regs apply to autotest cars, I remember when that came it, was part of the reason I stopped. Road going class had to be MOT capable thus the mods Roy is making wouldn't pass scrutineering. Not a problem if Roy is in the kit/modified class but they are the hardest classes.
Adrian is spot-on. While I'm keen to make sure that any highway-unfriendly alterations are easy to un-do, it's very much only the Blue Book that's worrying me for now. And even that clearly defines the operation of diagonal brake circuits, etc. And everything on an MSA event must comply, even Autotest cars!
The only regs Roy has to worry about is the little blue book as it's an autotest special - currently not for road use, in fact I'm not sure MSA guidelines apply to autotest cars.
The C+U regs and MOT rules are out of sync on many things.but EU law states that a car that is legal in one country will be legal in all.
Thus Hid. lights and LED lights are legal on new cars but don't comply with C+U regs
The service brake is required to work on all 4 wheels which is part of construction and use and therefore failure to comply when used on the public highway would constitute dangerously defective which is criminal offence and could see your car seized and crushed
"i believe a hydraulic hand brake is illegal as it has to be of a mechanical design able to work if the hydraulic system fails." Correct, but cars with electric hand brakes are not being failed under this rule. Its where the MOT and the type approval reg differs as type approval requires that the parking brake must be a separate system to the service brake but does not specifically require a mechanical parking brake. So you could use a hydraulic hand brake acting on separate wheel cylinders and it would pass type approval for mass manufacture. I can see the MOT rule being re-written soon as a button on the dash that tells an ecu to act on servo's that apply the parking brake is hardly a mechanical device!
Absolutely Dave - there's pretty clear guidelines for how the brakes should work. This does not comply. But, removing the reservoir and reinstating the pipe would keep the MoT man happy, as the mechanical handbrake is still in place too.
