Simplest way to explain. wear safty glasses and make sure to protect everthing that might get brake fluid on it 1 remove brake line from yhe master 2 fill resivor 3 squeeze brake lever 4 seal off hole where brake line was attached 5 release brake lever 6 wait a second 7 remove whatever you sealed brakeline hole with repeat from step 3 on making sure resivor doesn't go dry should take only 2 or 3 tries to get a good shot of fluid each time you sqeeze the lever
alright i ran a whole reservoir of fluid through it using this method. Is it spose to shoot out or trickle out... all i got was a trickle. might be time for a new one huh?...
Yes or maybe try taking it apart and take a look.All the parts are available would just need to do some crosschecking.I bet DOT3 was run through or the seals just dried out.Maybe just take it apart and barring any defects just soak the cupseals in dot4 and try again.
dot3 was definably ran through it... I've never rebuilt a master cylinder before........can i learn quickly or better off buying a new?..... PS do all atv models use the same size banjo bolts,,, aka can i buy a cheapy honda master on ebay..??
You can buy a cheap cannondale master.Stick with Cannondale since it is matched to our caliper piston size.Not sure what using a different master would do.As far as rebuilding the old one go for it.you have nothing to lose.They are not that complicated.
I use a honda trx450r master cylinder, it is a direct bolt on. Fairly cheap on ebay. It doesn't perform any better, but it has an adjustable lever, which is nice.
