I've come across 2 recent issues, and since they have to do with brakes, i figured it's best to fix it asap, but idk where to start. A few weeks ago, my rims started to develop strange spots on them. That is the very least of the 2 problems, but I believe it is related to the other one. The other day, my light came on saying I had low brake fluid. Twas true, so I refilled it. However, I have done brake work recently enough to where there is absolutely no reason the brake fluid should be that low. I theorized that the spots on my rims were brake fluid leaking out, and leaving a spot behind where it dried. Sometimes there are places where it appeared to just run out when the car was stopped, leaving a line rather than a splatter spot, which it what made me think of a leak. However, what puzzled me was this: what would compel my car to spring a leak on all 4 calipers at the same time?

Has anyone else ran across a mass brake leak like this before? Or know of any reasons it might do this?

 

If you're leaking brake fluid, your brake pedal shouldn't hold constant pressure when you put your foot down on it.

Check the bleeders on your calipers. It sounds like they are not tightned down all the way if ALL four wheels leave lines.

 

Go over everewhere you worked and see if its wet. If it is, clean and dry it, top up the fluid and keep an eye on everything. If theres a leel you will know where it is.
