The setup is a servo assisted , with 71 calipers.
I'm loosing a little fluid in the reservoir but can't find any visible leaks or weeps - I haven't taken the rear hubs off yet to check the cylinders.
Couple this small drop in fluid [say a couple of mm over a long weekend away], with a pedal that sometimes feels very low and soft, the brakes work but the brake activating position on the pedal changes and the pedal almost seems to get stuck down low and won't return, and you have to lift it with your foot??? (the return spring is fitted and not broken)
It's not physically catching anywhere (first thing I checked), and it doesn't do it all the time, it is very much like when you're bleeding the brakes, so I presume I have a leak somewhere but I just can't find it as yet.
What does a MC who's seals are failing feel like?
What's the best order of checks to perform?
It doesn't do it all the time and once it's been pressed down to the 'wrong' position it seems to then hold good pressure at the pedal at the position is normal again for what seems awhile, it does appear to be connected with stopping.
start journey - pedal soft - pumps up is pretty much ok but not perfect at all times...then stop for awhile. The pedal can be ok or it be soft.
Then add the final thing that with reasonable force braking, it pulls to the nearside a fair bit.....
Where should I start, I'm comfortable with spannering, but jobs like brakes I know there is a good order to the fault finding and an order that will hinder the fix!
I'll pop back in here later ....thanx very much in advance....
