    Hey guys, I wish to uprate my braking system, starting first with shortening the pedal travel. I've read on a site that if you use E46 330i front calipers and discs, with Z3 carriers, then they will bolt straight onto an E36 strut, but you get long pedal travel, so to compensate, use an E36 M3 servo and master cylinder.

    So, If I JUST change my 323i servo and master cylinder to an M3 unit, keep my standard brakes as they are for now, then do I get very minimal brake pedal travel to stop? I've just checked the part numbers on RealOEM, and my car HAS ASC, and says I have an ATE servo, but the M3 of the same year, 1997, has a Lucas. Can I just stick the M3 Lucas servo and master cylinder on in place of my ATE or is that too easy?

    There are 2 designs of mastercylinder/fluid tank. For your car, i think you will need M3 3.2, as the pipes changed at about 96.

    M52 usually needs M3 3.2, M50 needs M3 3.0.
    For iS and 4cyl, look to see what type does match the look.

    Ic, I'll have to give the part number to whoever I get the servo off then to make they are correct. fanx. So it' doesn't matter that the 2 makes are different then? Mine has an ATE servo, but RealOEM says the M3 of the same year, 1997, has a Lucas.

    Take a look at your cylinder and check the pipes
    http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=110549445395
    This is 3.2, with the connections facing each other for the master cylinder

    http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=250587603076
    This is the other type which is like M3 3.0 with connections that are straight.

    Then you can tell 3.0 or 3.2 system

    Yup, luckily, I just went out to check which cylinder I have, and my pipe stick out straight, not angled, Phewwww. So I need an early model M3 servo, cylinder and bottle then, fanx for that. Could've been a costly mistake!!

    I've never uprated my master cylinder or servo on either of my conversions and never experienced this long travel?

    Oh,Heres the link to a site that says to get the master cylinder and servo done.

    http://www.strikeengine.com/bmw-tuni...36-tuning.html

    I also spoke to Chris at CRM, and he said he does that conversion too, fit the M3 EVO servo and master cylinder for the 330 front brake conversion. However, he did sya I needed the EVO cylinder, which has only 2 pipes going to the cylinder, and NO pipes going to the fluid bottle, same as what I have right now. But the EVO cylinder has the pipes going in at an angle, but he said I would need to bend the brake pipes slightly to angle them in correctly.

    £50 ex. delivery was cheap. Am gna be popping into Quarry Motors on Tuesday to get the 330 calipers and carriers.

    Here is a link to a US site that recommends doing the front AND rear brake conversion. Has anyone done both front and rear conversion? Or should I just do the fronts only?

    Hang on a mo...
    " There are two advantages to using the E46 rotor on the rear. Not only are they 3/8" larger, but they are also vented. Installation is identical to the front conversion. The E46 calipers must be used under at least a 16" wheel."

    If you want vented rears, you can get them from 323s or 328s.
    http://www.realoem.com/bmw/partxref....r=1&series=E36

    You'll probably already have them.
    I had a feeling the original handbrake shoes are too small for the larger drum bit of 330 rear discs.

    Hi.

    Just completed my 330 brake upgrade. Had been running fronts for about a year and was pretty happy with improvement. Any way the fronts were getting a bit tired so started looking for the rears and luck would have a member was selling a full set with PF pads and hoses. After a little hard Persuasion tactics i manged to get the rears both sets of pads and hoses for 200 quid. Bonus !!!!!











    Fitting was fairly straight forward, A little cutting of the rear disc protectors to get clearance was all that was needed. Still haven't fitted the rear shoes but will get round to just before my MOT is due.
    I got hold of m3 3.o servo a wee while ago but still haven't fitted that yet , even though they are great i think to get the full benifit i'll have to do it sooner then latter. Running in the brakes carefully with the old brake hard from 60 to 10 mph 6 or 7 times method, making sure not sit on the the brakes at a standstill. Means now the brakes are truely staggering. Getting used to the noise takes a little time but boy o boy do i love my brakes

    Cheers D.
