Well this is the second MC and the rubber gaskets are leaking and the damn theing is brand new does anybody have any tips on stopping this or if i did something wrong or how i can stop this from leaking im just about to the point of puuting 100 lbs of (C-4) on the car and watching it blow to pieces

 

I used two large hose clamps to clamp the reservour to the MC. Most people do not like this method as they see it as a bandaid, but it has worked for me for 3 years. No leaks.

Just be careful and do not overtighten the hose clamps. That can crack the plastic and make things worse.

let me get this right you never took the clamps off??

 

im in the same boat as you. i get new brake lines from master cylinder back (couldve SWORN it was a leak) no fix, so i buy a new master cylinder, no fix. turns out the brake booster's shot but i just picked up a new one twenty minutes ago so im gonna go put it in! if this doesnt work ill sell the car and buy a civic. good luck with your brakes!

 

yup. one clamp on each side of the cap, looped around the bottom the the MC.

where exactly is it leaking???

If it is the rubber bushings between the resivor and the master cyl, they can be replaced for under $10 in parts.

Of course if that is the location of the leak, then either there is a installation error (and someone needs remedial auto mechanics 101), or someone is putting weight on the resivor (like a hand when leaning in). Either way, C4 should not be used, except for maybe on who ever is working on the car.

 

it is leaking between the resivor and mc and can you get new rubber bushing at like auto zone or do i have to go to mazda

 

Naughty, naughty...No bumping...

Just call your local auto parts store and see if they have them. Our MC's aren't a unique RX-7 part, you know...

 

last set I got was $8 from Mazda
