Hi guys... The brake master cylinder on my M3 has failed leaving a very soft and long pedal...Not good... What's worse is that the seal repair/service kits are NLA and a new cylinder is £670 +VAT!! Does anyone know where I can get one from at a more realistic cost? Alternatively I would be looking to get my existing one rebuilt or perhaps fit an aftermarket cylinder...Anyone done this or have any recommendations? ------------- 1987 E30 M3 1996 E36 328i SE 4dr (Manual) 1992 E34 525iX Touring...SOLD |

http://www.c3bmw.co.uk/StockItem.asp?categoryID=47&subcategoryID=0&productID=1136&oRef=-1§ion=2&Item=unassign - C3BMW sell the 25mm 'big bore' master cylinder, gives a firmer pedal feel than standard too. I can't believe the price BMW want for a new one........  -------------

Thanks, Sporty...I found this, too....and their cylinder @ £199 includes VAT and also includes a replacement brake pipe as the 25mm (7 series) cylinder has 2 x 10mm thread connections where the E30 M3 (23.8mm) one has 1 x 10mm and 1 x 12mm. It's also an ATE o/e spec...definitely cheaper than main dealer even for that item!! Gonna be ordering one today, I reckon. ------------- 1987 E30 M3 1996 E36 328i SE 4dr (Manual) 1992 E34 525iX Touring...SOLD |

I wouldn't buy a used one of unknown origin. But hell, it's just for the brakes, nothing important....  ------------- E61 520d, slow and buzzy but my wallet likes the mpg..... |
