Wild problem with brakes...

[rockaria]

Hello Everyone,

Here is a new one that maybe someone can help out on. My car runs and brakes perfectly. Well it did. I have owned it over a year and never had a problem with the brakes. My MC had a bad seal and I replaced the MC with a 19mm one. adfter that it still worked perfectly for months. Then the rains came. In the past week I have had the car in more rain than I can take. Big puddles of water in the road and spashing everywhere.

Now, It drove to work perfectly this morning. Solid as a rock. Then it really rained, and hard. It stoped raining by the end of work and I got in it to go home. The brakes fealt really spongy and went half way to the floor and needed pumping to stiffen up. I drove it a while and checked and the fluid level is still perfect. But I need to pump it to make it stop. The peddle never goes all the way to the floor, but it is not as stiff as it was.

Any ideas? I can find no leaks anywhere. and it all seems to coincide with the rains and humidity we normally do not have.

Thanks,

I suspect that it's just a coinsidence that it's raining & no brakes.

That being said, it sounds to me like a seal in the MC went bad. You might just try bleeding the brakes & see what happens. I once had a similar problem with my BMW & after bleading the brakes everything returned to normal. The one thing I noticed was how filthy the brake fluid was and I assumed that some grit may have affected the MC. It's been working perfectly for years since then.

Bleed the brakes before anything else. It's like changing the baby's diapers or taking out the trash. In other words, pretty routine.

Well I adjusted the rear caliper venting cearance and bled them and it is all better now.

Wild... I have a feeling its a moisture related thing, but how can moister get it without fluid getting out.

Oh well, Pookie is 100% again...

Thanks for all the advice, worked like a charm.
