Installing Big Brake Kit... Need Some Answers
Ok... so I over torqued a banjo fitting on my BBK... The bolt, the line, and the threads on the caliper are fine but the crush washers are no good.
My install instructions are in Japanese and I can actually read most of the Hiragana and Katakana but not the Kanji. Anyway, Google translator generally does an OK job but not with these instructions... I've done this install one other time but it was 10 years ago. So my questions are: 1) What is a safe value to torque a banjo fitting to on a aftermarket forged aluminum caliper? I've seen between 13 ft/lbs and 30 ft/lbs during my recent research. I'm thinking of going to 15 ft/lbs. 2) Where can I purchase crush washers with the following dimensions?: Outside diameter 14mm; Inside diameter 10mm; Thickness of 1.5mm; and 1.0 thread pitch. 3) Worst case scenario... could I reuse the OEM crush washers? They almost match the dimensions of the crush washers that came with my kit except for the outside diameter which is 16.16mm. OEM crush washer on the right Thanks in advance. projekt zeal86 build Last edited by zeal86; 04-07-2015 at 09:49 PM. |

Bring the banjo to a local parts store, my local napa has a bin of assorted crush washers.

I had a similar problem with Hayabusa brakes and an old mechanic told me to scorch the old cooper crush washers with a lighter. I don't know why, but it worked. Good luck buddy, hope this helps

@Ultramaroon I think I might try 15 ft/lbs but I still want to wait on some more input.
I really don't want brake fluid running down my calipers on to my wheels. That would suck! Gotta get it right this time. projekt zeal86 build |

So what torque values do Essex, StopTech, Wilwood, Project Mu, AP Racing, etc... instructions suggest or state for the proper torque at the banjo fitting?
My Runduce calipers are made of forged aluminum. Not sure what metal the banjo bolt consist of but it is a 10mm x 1.0tp. I've seen between 13 ft/lbs and 30 ft/lbs during my recent searches. I'm thinking of going to 15 ft/lbs but before I do I would like some more input. Thanks in advance! projekt zeal86 build |
