son of stig Posted May 21, 2009 Report Posted May 21, 2009 Hey all, Just wondering if anyone here has installed a KE3x/5x brake booster/master onto a ke20? Ive seen a couple of KE20s with the big ugly rectangular PBR setup (like KE55), was this a factory instalment on the late models? Curious as to whether the pedal setup or bolt holes in the firewall are different. Any info much appreciated! Cheers, Paul Quote
rob83ke70 Posted May 23, 2009 Report Posted May 23, 2009 only what i've seen in photos, vh44 remote booster mounted on passenger's side of firewall seems to be the go. thats about all the info i'm good for at the moment though. robert. Quote
son of stig Posted May 23, 2009 Author Report Posted May 23, 2009 (edited) Why bother? Just curious as i have all the bits lying around, i like seeing what can be mixed and matched. And have seen a couple of photos of KE2x engine bays with the same setup. Ive looked at my KE20, KE35, and KE55 today and scoped off the car spares. From the looks of it all it would need is 4 holes drilled through the firewall to mount the booster and possibly a bit of reinforcing, the rest should line up. this pic was from seabiscuits for sale thread: Edited May 23, 2009 by son of stig Quote
Redwarf Posted May 23, 2009 Report Posted May 23, 2009 By all means change it to a twin system (a very good idea...) but i can't see the point in a booster on a sub 900 kg car, when even "Big brakes" aren't even that big. I've had a 25 for nearly 20 years andd never felt the need..... Quote
son of stig Posted May 23, 2009 Author Report Posted May 23, 2009 When you say twin system do you mean the later KE2x master with the single reservoir and twin outlet, or the KE3x master with the twin reservoirs? I'm leaning towards the former. Anywho, thanks for the advice. Quote
Redwarf Posted May 23, 2009 Report Posted May 23, 2009 Well, actually I've had Suzuki Swift, and now GD Gallant. Split tanks so if one system craps out, you still have something to play with. Quote
rob83ke70 Posted May 24, 2009 Report Posted May 24, 2009 the thought of a single system scares me somewhat. I've only driven the one car without vac assist, and the brakes weren't overly brilliant on that, it was a morris 1100 sedan. I'm going to be the proud owner of a ke11 in the not too distant future, and I'm going to put ke70 front brakes on it, and probably a twin circuit system. The vac assist i will make up my mind when I get there. On the other side of the whole vac assist argument, I find some cars with too much vac assist somewhat scary as well, a peugeot 407 coupe fitted with a dt17bted4 twin turbo common rail v6 diesel has huge vacuum assist, and if it fails, you CAN'T pull the car up, I've tried, at 20km/hr you swing off the steering wheel and STAND on the brakes and it doesn't really pull up...

philbey Posted May 25, 2009 Report Posted May 25, 2009 I've got a VH44 on mine and I'm going to rip it out for two reasons: I'm lacking Vacuum with the Dellorto (plus I can't be bothered tapping into a runner) and the thing takes up a large amount of space in the engine bay. I'm probably going to upgrade to a Swift/Galant item, and increase diameter which should give me more brake power. Dwarf, did you use the 17.46mm or the 20.64mm masters? Both the Swift and the Galant run those sizes (I forget the obscure Imperial fractions) Quote
Redwarf Posted May 25, 2009 Report Posted May 25, 2009 Size always matters. :dance: Gallant also has a size inbetween as well, I think. I used the GD one, 13/16". Swift one doesn't fit as nice, and I never really liked the one I had. (But hey, it took 15 years for me to change it.....) Haven't driven it with the new one yet though. Plus side: Swift has remote reservoir. GD is long and thin with compact tanks. Neg side: Both are worth their weight in myrrh to buy new. Quote
philbey Posted May 25, 2009 Report Posted May 25, 2009 I got quoted 153 for a Galant one from a brake joint, not sure what size though. Motor traders were about 50 bucks more expensive. Good deal I thought? Quote
KEI069 Posted May 25, 2009 Report Posted May 25, 2009 I got quoted 153 for a Galant one from a brake joint, not sure what size though. Motor traders were about 50 bucks more expensive. Good deal I thought? Mazda RX4 master works really nice on a KE10 with minimal modifications to the firewall. Quote

Plus side: Swift has remote reservoir. GD is long and thin with compact tanks. Neg side: Both are worth their weight in myrrh to buy new. So the Galant master is sounding like a good idea. I did scope one out at the wreckers last time i was there but didnt have time to pull it off and test fit it on the ke20 thats also there. Are there any mods involved? ie drilling/enlarging holes, changing of brake line sizes, or changing length of the rod that goes to the pedal? I can take care of these, just curious before i start the endeavour. I appreciate the time taken in replies guys. Quote
