Brake fluid bleed problem solved.

[secretagentmole]

Changed the seals on the front caliper and I could not get the damned system to prime after I had bolted it all back together! Tried tying the brake handle to the handlebar, no joy, tried half pulls, no joy.

Screwfix sell a plastic 1 litre syringe which comes with a length of clear hose, supposedly for draining the oil out of things with no drain hole, like some old lawnmowers. This hose fits neatly over a bleed nipple after warming in hot water, hose on, crack open nipple, pull on syringe, pulls brake fluid through system.

Cost? £9.99 inc VAT

there was probably air trapped in the master cylinder common problem

cracking the banjo bolts can free it and get you going

pulling and holding the lever does nothing despite what others say

[cockercas]

Crack banjo bolts or bleed nipple if the mc has one.

If you have a res on a tube then fill it and start squeezing the tube and it will fill the mc.

Banjo bolts were cracked open and washers replaced, it just would not charge the master cylinder. That syringe just pulled it through nicely!

I mean pump the lever up and crack the bolts or crack the bolt on the M/C and pump lever till you get some fluid there

I did, I cracked the bleed nipple open, no joy, lower banjo, no joy, so got this syringe for under a tenner and sucked the air through. Worked like a charm!

Did you crack the banjo at the master cylinder?

Ive never understood why people struggle to bleed brakes.

Its one of the easiest jobs to do.

actually it really does depend on the calipers and set up in question!

I have had some systems bleed up perfect straight away

But I have had more systems point blank refuse to work! or air getting trapped somewhere especially in the older tokico calipers! now they was a bad design

What is it they say about workmen and tools?

Tokicos are fine so long as you don't mind unbolting them and jiggling them about mid-bleed.

Reverse bleeding with a syringe is my current favorite way of doing brakes. Why bother trying to force trapped air upwards when it's much easier to push it upwards?

[Stu]

Only one tool needed in bleeding brakes and that's a spanner for the nipple!

Nothing wrong with my spanners

[Mr Fro]

Two tools needed in bleeding brakes - one's a spanner, the others got nipples!

Fixed.

Dont think that's fair calling me a tool

Ducati clutch is the worst ive done.

And i did that so many times, thats probaly why im so good at it, and the fact i change my fluid every two days.

[Stu]

Yeah it gets easier with practice

You will just bleed the new fluid through though won't you? different story starting with a dry system
