I've started looking for one of these but I'm pretty much clueless about which ones are good quality, what type of master cylinder I'd need etc. It would be going into a classic shell.

OBP do some good kits,back in the day when i was looking at fitting one to my car...You looking at doing motorsport? that is the only reason that i never went for one in the end as i also drive my car on the road.SJ.

Yes mate, I'm mainly focused on hillclimbing but I've been itching to have a go at Formula G for some time now... I've seen a couple of those kits on Demon Tweeks. I've also had a look at Compbrake's kits but not sure how good they are or also what I need exactly. What sort of master cylinder, bias valve, and so on.

COOLMate have a look at this:https://obpltd.wordpress.com/2010/09...-tech-session/...it might give you a Head start,i know that when i was thinking of fitting one i done a little research and it seemed straight forward enough.SJ.

Don’t buy an OBP thier braking products are a load of cheap crap. Pedal boxes and handbrakes that flex badly

Hi mate a friend with a time attack car. He only used it once and complained it didn’t feel right. When we looked there was severe deflection in the pedal box. That’s why when I fitted my handbrake I avoided them. I think thier catch cans etc are ok tho

That doesn’t sound good,and to think that their was a time,when i was going to part with my hard earned money for one of those...To the OP i would avoid OBP one then mate.Thanks for that Joe.SJ.

i don’t I’m afraid, pretty much everything Subaru has gone now, apart from a rear brembo setup with nearly new discs and pads

joe v3sti

yeah deffo avoid mate, I would be going Ap only for a pedal box. Although personally I stayed servo assisted. I’ve a number of friends who haven’t and non of them speak highly of the obp stuff

I remember now I also had a friend who used obp habdbrake and the cheapo brake cylinder exploded on track.

I actually ordered 3 different handbrakes before settling on this one. Quality is excellent and uses a quality girling cylinder.
I welded a sealed platform next to my transmission tunnel to mount it on, a number of friends have since switched to these

There's a thread on hydraulic handbrake in the braking section dated 21 Jan this year.

Thanks Joe. I'm keen to know more about the advantages/disadvantages of single vs twin cylinders. I'll have a read of the link above now.

You’ll need a 2port new age MC, remove the OE balance bar.
One port feeds the front, one feeds the rear.
Come out of the front port into a T then to front callipers
Come out of the rear port, down towards the back of the car. Into the brake bias valve. (Buy a Tilton one not cheap rubbish)
out of the bias valve into the single cylinder handbrake.
Out of the handbrake towards the back of the car, into a T then to the rear callipers. Simple !


In hillcliming its only really used for the launch. However really this needs coupling with a very good launch control strategy to get the best out of the setup. Not some crappy pops and bangs rubbish. At which point you can adjust the launch strategy accordingly.

For or years I just used the oem handbrake and that worked superb. Originally I taped the button in with insulation tape. Then later pinned it. The launches were on par with the hydro.

To do a handbrake properly your looking at around £350 minamun. That’s for MC, brake bias valve, handbrake, custom Hel lines.
So it’s not a cheap job. Depending on the spec of your car £350 could be spent else where to make you go quicker. New tyres, not used etc proper sprint brake pads. There’s loads of stuff, just depends how important the handbrake is, many do it for looks

£350 sounds reasonable to me tbh. Off the top of my head I actually thought that the hydro cylinder was only teed into the rear brakes. When you say custom HEL lines, are you meaning as in braided hoses from the bias valve back? Will they just make these on request if I provide measurements?

I'm actually building the Type R now. Just bought a forged EJ207 block and got a six speed on the way. I'm not really wanting the hydro for hillclimbing but more for Formula G next year.

The handbrake M/cyl goes into the rear brake line. 2 ports, one in, one out. That assumes you're not running abs. If you are, you need a specialised cyl.
Pipes can be normal steel ones, cut and flared to length. Most garages can make those.

I can make the lines up, that's not a problem. No ABS as it's a V3 Type R.

Joe, what you said about the Newage MC, did you mean the main one in the bay or did you mean for the handbrake itself? I'm still a bit confused about how these work. I actually though you had the front brakes left untouched, and then the rear lines from the MC went into the hydro.
