After a disastrous attempt some years back on an old Montesa Cota 304, I finally bit the bullet last night and did the brakes and clutch on the GG.

It all seemed too easy...
- remove reservoir cover
- attach tube to bleed valve
- open valve a quarter turn
- pull brake lever in
- close valve
- let lever out
- repeat unit new fluid flushes through, topping up reservoir with new fluid as required...

Did I miss anything?

Hi Keith

Sounds like you've cracked it but if you've still got air in the system here's a trick we used to use on the racing bikes.

Same process but in reverse - you need a syringe which you fill with fluid, then attached to your tube on the nipple, pull in the lever and force the fluid up the other way - pushes out any pesky little air bubbles trapped in the system - do it carefully or you'll end up with fluid on the shed roof...

Also helps if the fluid is warm (not hot!!!)

Ive been trying to track down anybody that owned a 304 that the tank paint didn't blister and fall off. What happened to yours????

I repainted some new ones for Lyall O'Brien in about 86 using fibreglass resin to try and seal the plastic before painting, never found out if it worked.

Blistered and fell off...

I ended up using a straight enamel gloss red paint. No primer. It still bubbled, but not as much as other attempts.

Best way to fix it permanently is to sell it!
