Recommended Posts

im at the stage where i am wanting to maodify the brake boost on my mk2 escort so i can run side drafts etc. iv heard of people running remote boosters in line, and also re mounting existing booster lower. im not that knowledgeable in this area and its pretty much the last thing left on the to-do list before i paint the engine bay and new engine goes in. can anyone please provide me with some good advice in this area? that would be mint. cheers, cam

If you don't mind having a heavier pedal just mount the master on the firewall and ditch the booster all together.

I'm going to do this on my car soon.

I disconnected the vacuum pipe to it so its not vacuum assisting at all and the pedal still feels pretty light, not a problem at all. On a sub 1000kg car I don't think you need a booster unless you have gigantasaur oversized brakes or are literally a nana with like saggy boobs and 37 grand children.

A remote booster (like a VH40) can go anywhere. I have seen them (a pair of them in this case) mounted on the rear seat firewall

/i can sell you a mint remote booster

ditching the booster doesnt sound like a bad idea, but not knowing how exactly its going to be like, i dont know if i want to risk it.

remote boosters sound like a better idea, but me not knowing exactly how they work makes it difficult to justify.

can anyone point me in the direction of some education about this?

what is the remote booster out of? and where would i mount it? and how do i go about doing this, is what i want to know.

on the side, someone tried to explain to me that you only need 1 booster if it is run in-line which from what i understand is most common. other wise you need 1 for each side? does this sound right?

vh40's and vh44's came out in the likes of minis and hillman hunters, they are single circuit. so if you want to boost both front and rear brakes you'll need 2 of them. I've heard you can get away with running just one to boost the front if you fit larger slave cylinders into the drums at the back, though i havent done it, it'd be a good point to start researching to confirm. safe r brakes in chch sell vh44's for $500 each brand spankers.

I'm having similar problems with my car, still havent sorted out what to do as my engine takes up the space where the brake booster once was, i reckon a booster is needed on a road car, especially if your running big calipers otherwise the brakes wouldnt modulate very well.

hope that helps/ raises more discussion 8)

yea i was talking to my mate at work and he said that they dont run boosters at all in their stock cars and he thinks that it shouldnt be too bad to do it in my car.

im running standard callipers but ferodo formula 2000 semi - race pads which think will bite pretty hard (at the cost of wearing out quickly) so with that in mind, running no booster could be do-able. what does anyone think about this?

if i boost the brakes, will most likely do just the fronts, and later on possibly fit up a hydrolic handbrake for the rear.

crazy rich, whats the story with your car?/what is it?

theres also tricky dicky ways around it with running a larger ID brake master cylinder, my fluid dynamics is crap at the best of times but from my limited understanding this gives you more torque applied to your discs/whatever but less travel.

my ke20 has a mitsi canter master cylinder of all things

vvega could explain better

I went and talked to the cert guy yesterday, and hes all good with me making up some linkages to run the booster and cylinder under the dash, like this

but he did say that hiace vans are like this from factory

though you probably dont wanna go to such hassle with your car, there really isnt much occupying the space above the accel pedal once the ducting for the vent is removed, so i think theres room, in a capri anyway.

I take it it's a xflow motor?

Why not use the 1300 manifold. It's angles upward slightly so it clears the booster. Palmside in chch has them in stock. Thats what they recommended for my Esky. Much easier than mucking around with the booster!

Would that manifold allow him to run sidedrafts? I don't know my esky stz but surely you mean just a standard one.

If you disconnect the brake booster vacuum that will show you what its like with no booster

im thinking along the same lines as you, allthough funnily enough i talked to a guy that did this except he didnt know much about it so couldnt get many answers. this could be the way to go though. pedal box would be nice also.

One of my mates had an Escort rally car years ago. It didn't even need a booster. It started off as an 1100 with drums all round, he got front discs from a 1300 from memory. No booster needed, raced it like that no probs. That was with a hotted up 2 litre fitted.

Nah. A manifold that suits twin sidies. that way you can still run booster. Only need to delete booster if you put big cam in engine( cause it won't produce enough vacuum for the booster).
