Hi,
I own a 1990 TRX 300 Big Red. I recently decided to overhaul the front brakes on the bike and replace the fluid. However I'm unable to achieve a good brake lever after bleeding. The shoes are all adjusted correctly, both cylinders are free and there are no blockages in lines etc. I've spent hours trying to bleed the system but still end up with little or no brake! The master cylinder/lever has also been rebuilt with a new kit, but this has not helped.
I've tried back-bleeding several times from the cylinders up and also pressure bled the system, but still nothing. There is fluid getting to both cylinders and the lever seems to be pumping through. Once I tighten up the bleed screws the lever remains spongy with some brake effort but nowhere near enough to stop the bike safely! I'm now fed up of wasting brake fluid and spilling it all over the freshly painted fuel tank!
Any suggestions would be very much appreciated.
Thanks,
Bruce
