Hi
My Specialized stumpys off the road (or trail) at the mo as the seals failed inside the Avid rear lever and I can't find a service / internals kit for this bike anywhere, even Avid don't have stock or an ETA
So, any suggestions, part number is A150640A apparently.
cheers
if the seals have failed in the master cylinder (brake lever) its normally problematic of a wider degradation of rubber parts across the entire brake; this is especially true of pre-2012 Avid brakes
DOT fluid is corrosive and attacks rubber parts in the brake system.
Avid switched to using Nalgene for the MC diaphragm for 2012 brakes onwards as they had such high warranty return numbers from pin-hole leaks developing in the older diaphragm material.
I would not waste any money attempting to fix with parts and your time, but find some cheap Shimano SLX brakes and adapters on-line, clean your Avid rotors up with disc brake cleaner and then enjoy a much more durable brake system with great modulation
I work as a bike mechanic in case you are wondering, and have used SRAM's warranty department way too much for customers...

Under a fiver
thanks for the help folks
I followed torsoinalake link and bought a couple of seals from Bikegoo (£1.99 and 60p postage I think) - they arrived today and just fitted and bled them up - and at last its all good again! The Avid bleed kit isn't very good either though!
Esher-Shore - I'll probably follow your suggestion should this happen again, I've had Shimanos on my other bike (Kona) for years now without any issues (or bleeding maintenance) whatsoever
Anyway, cheers again!
