coloured hel lines............Need the patience of a saint.....& i aint one!!! GRRRRR

[Flyingscotsman3]

Hi All,Decided to put transparent red hel lines on my classic back & front, dropping to 2 lines on the front & doing away with the splitter, gold HH pads all round & DOT 5 fluid replacement.I done this years ago on my old zx12, & a busa before that, & it improved braking loads.
All connected up, the back was fine & done bleeding in 15 min with a good brake.The fronts are a pain though,they have got fluid in both lines coming out fine a the nipples (using a sealey vacum bleeder).....but still no feeling of pressure at the lever. I know i pushed the pistons back in a bit, to get the new pads in, & this is prob what`s happening.As i finished in the garage earlier, i tied the lever back to the throttle grip overnight to see if this would help any.
Any advice, or do i just have to keep pumping the brake, & keep bleeding the system?.
Cheers & Thanks in advance..... Kev

P.S The hel lines look great!!............ be even better when the brakes work too!! .

OK - Having just replaced my fronts with Goodridge buldaline. You're not bleeding correctly.

1) Push the pistons RIGHT back into the callipers.
2) Flush right through with more clean fluid using gravity alone. - If you've moved to silicone Dot5 (as opposed to mineral 5.1) then YOU MUST PURGE all remnants of Dot 4 out. Bleeding does not flush what's behind pistons.
3) Make sure all bleeds and banjos are tight. If in doubt - replace copper washers with dowty seals.
4) Start pumping - gently. About 5 full pumps - wait 5s and then gently squeeze just enough for air to bubble out of the tiny equalising hole in the MC.
5) Repeat until you win. Took me no time at all. PATIENCE.

Oh it's important that the M/C is at the highest point of the circuit. Otherwise the bubbles will not come out. And better where it's warm and dry.

In the end stripped both calipers, cleaned the pistons with brake cleaner & re-greased with copperease.I think that they were a bit on the sticky side, but not all that much really.If there is a fault, it`s maybe just that the m/c is not very powerful, to the point of struggling to push the pistons out from the fully back position.
Cleaned & lubed they both bled up to a good brake in 15 minutes, so ta for the reply`s & another happy bunny that can get back out on his bike :-?. Thanks again Kev
