Hi folks, long toime since I posted, but I'm doing some work on judodave's 650z and wonder if anyone can help.
We're having an almighty problem getting the front brakes lever to go firm, but I'm stumped to know what else to try. I seem to recall my previous 650 never had a very firm lever, but can't say if it was like thi one or better.
Anyway, the bike's got new pads, new pistons and seals in both calipers, new master cylinder seal kit, a new 'o' ring around the base of the plastic master cylinder reservoir. Just about everything, except the hoses are new.
I've tried bleeding with a syringe by sucking fluid through from the reservoir down and out the bleed nipples, and also by pumping fluid the other way (into nipple until it comes out of reervoir). I've also done the traditional undo nipple-piull lever-do up nipple-release lever etc way. None of them make it any better which makes me think I've got the best I can expect.
I can get the wheel to brake hard when pushing the bike along using about 1/2 - 3/4 lever travel and it feels firm, but the lever never goes solid. With more pressure you can always squeeze the lever harder which seems wrong, even though the brake performance might be OK.
I recall my previous one was a bit like that, but that was few years ago. Does that sound 'normal'. I've got an MOT booked in the week.
Anything else these 650's are known for in the braking department that I should check?
thanks, Phil
