Brake Mater Cyl Prob

[sencaw]

Ok, this just started - My brake master cylinder is leaking - drains the reservoir overnight while sitting - looks like it running down the front of the big round thing where the reservoir connects to it. Is there a gasket there or is it something else.

 

Thanks in advance for all your help

FWIW I think it was only like 20-30 bucks for a master(new) last time I did one, fairly simple job as well...

Yeah, for what the dealer would probably want for just the seal, you could probably get a whole new MC at NAPA. Hardest part is the bench bleed, which isn't hard.

Exactly, sounds like you blew a seal and now it's dripping...

The resivoir grommets on the master cylinfer are part number 46045-W1010 MSRP is $2.42 each. That's even less than the $20 master cylinder from the aftermarket parts house. If it's the piston side where it enters the booster it's $75-300 depending on if you can get away with the piston or if you have to change the assy, either way make sure you get a suction tool and vac out the brake fluid from the booster before you reassemble it.

Cool, shows you never know, some parts are and some parts aren't sold individually. Also some parts are reasonablely priced while others are obsurd.

yep, the biggest markup is on the cheap parts like nuts and bolts.
