Euro S50 and Brake Boosters

Why not relocate the whole thing behind the headlight and have all the room you need?

I tested the Geo Metro booster about 4 years ago and didn't really like it as it offered barely no assist.

geo Metro with BBK's is working pretty good on my car.. I wish I had a BMW booster though!!!

Today I ride my M3 with your M/C and the car brake less than my sister's brakeless bike :-?


I run oem pads, discs and calipers at 70% of life.


I can't lock the wheels in gravel and I run the car in tarmac and I almost injuried my quadriceps to obtain the same deceleration of this guy



What's up with this M/C??¿

e30 m3 master

The overall length is a concern as well, as mentioned here (http://r3vlimited.com/board/showpost...9&postcount=64) The Aisin setup is very short.

Compare the end of the MC to the beginning of the plenum inlet.



I wish I could remember what Aisin MC I went with....

The master is a bit long, it doesnt interfere with the CF box but the reservoir might. So I might do a lil bit of plumbing work to raise the reservoir.. I am still working on this swap and I am going perfect it as much as I can..

The Mercedes-Benz booster seems to be 2" smaller than the e21-2002 booster. I think it is a more acceptable method as it is accept a BMW/M-B MC without modification.

it looks relatively small but I dont know if that will work with the euro s50b32. I got the Geo booster to work with the e30 m3 MC for now. I am still searching for other options though. I think this set up will work fine.. I am all done just have tuck all the wires and clean up the engine bay then comes the bodywork/paint..

no its a euro M52. Just showing the room with the different MC.

[atldohc]

thats not a euro s50 engine

Here's some pics of the Mercedes 280SE master cylinder in the engine bay with the Golf MK I booster.







Plenty of room around the intake :)

Geo Metro booster

today we modified a Geo Metro booster (small version) and mate it with e30 m3 master cylinder. It wasnt a direct fit since we had to modify the MC housing and the inner shaft of the booster. I know it will be much better than having the Geo MC for sure..

I used a VW Golf (Rabbit) Mk I booster with a MB 280SE master cylinder. Its a 23mm bore straight through. Everything bolted together with no mods, and the brake feel and performance is excellent.

I am going to see how it goes with geo booster and the e30 m3 MC first.

that is VERY impressive. i "tried" that too. The geo booster has a smaller hole for the master to fit into. i cut that out and made an adapter bracket for the m3 master. i started to weld it onto the geo booster, smelt burning rubber and assumed i burn the inner diaphram ...... and the master hit the intake boot.... i ended up throwing everything in the metal bin.

NEVER found a solution I was happy with.
have a 3 pedal w/ tiltons now. very happy.

I just got smaller version on the Geo Metro and in the process of modifying the shaft and making the M3 master to fit. Its a lil work but I think I will get it done..
