Riebe M70x70 mm for rear caliper

[trond]

While splitting a set of 85 Carrerra rear calipers I damaged one of the M7x70mm bolts and need help either with getting a second hand caliper or just bolt and nut. Any advice on this ?

[Harpo]

The M7 bolts are very hard to find unless you just buy another caliper. Eric @ PMB might be able to help you

M7x70 mm with torx head BMW 11127535024. Torx Bolt Part #: 11-12-7-535-024-BOE at 2.25 from our host via BMW pages. Flange would have to be trimmed down and don't know pitch but have never seen anything but 1.0 pitch

German seller tola-tools-de has M7 but unfortunately dont sell out of Germany....
Zylinderschraube M7x70 DIN 912 12.9 brüniert. This one is with allen head and might work. IF I could get my hands on it

Very resourceful! Great find on the BMW part.

Always wondered if they could be drilled out to M8, myself....

I always wondered why ATE used such an 7ncommon sized fastener.

I went through this, called everyone/everywhere... ended up taking the board’s advice and drilled the bolt holes in the callipers a smidge larger then used readily-available bolts, fit perfect.

pictures of modified BMW M7x70 mm bolt part no 11127535024 and corresponding torx bit. Both trimmed down on my lathe and fit perfect ! The bolt is threaded the whole way and may be used on all rear calipers using 7 mm bolts
