Hey folks, a few weeks ago, I had my rotors/calipers up front replaced. I'v noticed while standing still at a light(or stop sign), the car rolls ever so slightly(like they're not holding) Now today when I changed the oil I was looking at things under the car, and noticed a few small spots of brake fluid on the inside of my right front tire, and a bit of fluid where the rubber hose goes into the caliper. Is there some sort of o-ring there, where the hose goes in? I looked at the line and it didn't looked cracked. I'm guessing this fluid loss is resulting in my slight roll issue. The driver side looks ok, all dry, could it be that hose is leaking, or the master cyl.?

Ugh, the fun never stops with the ol' thirdgen

 

If the hose connection is wet, then you definately need to take care of it asap. If this doesn't cure your problem, then move on to other things, but fix the leak first.

There aren't any o-rings, but there are copper crush or sealing washers there that seal the banjo fitting to to caliper when you tighten the banjo bolt down.

You should be able to get more crush washers at any auto parts store. If you end up replacing them, you will have to bleed the caliper that you put the washers on. You will have air in the lines that will have to be bleed out for your brakes to work correctly.

If you paid to have the work done, then I'd take it back to them and show them the wet brake line. They should take care of it for free. It's a 5 minute fix.

 

I would take it back to the place you had it done and tell them what's happening. I'm guessing that the fitting isn't tight, or the copper washers weren't replaced. When you tighten the line against the caliper, it crushes that copper washer and puts grooves in it for a good seal. If the old washer are used, they wont seal right and it will leak. They must be replaced every time that line is removed from the caliper. And also as alloy said, then you must bleed the system.

 

yeah, well alot of people think brake work is easy, but i've only met a handful of people in my life who can actually do a quality brake job.

If you're just doing it yourself, first see where the leak starts. I doubt it starts all the way up to the mc. Most likely it starts somewhere from the rubber hose to the caliper. Get a flare nut wrench (line wrench), and make sure the hose to the brake line connection is tight.

Check and make sure it actually has the two copper washers and that the bolt is tight.

If none of those...it could be possible that the caliper itself is leaking on the tire and it's flinging the brake fluid up in that area. I've seen alot of cheap rebuilt calipers that leak from day one.

Thats why i laugh whenever i rebuild my own calipers and i go to the parts store to get the o-ring and dust seal and the guy says "you know rebuilt calipers are only $12".
