Pardon My Ignorance

Okay, here's the deal. I had my brakes done 4-5 months ago, because the shoes were worn, also had the rotors replaced. Today, my brakes seem soft and at full push on the pedal the "brake light" comes on. I pull the top off of the reservoir and the back section is full, but the front section is empty. Where is it leaking? Wheel cylinder, Master cylinder, other?

Back passenger side drum looks a little wet. Is this the prob?

I filled the front reservoir and drove it around the neighborhood and all seems good, now.

What do you experts say???

If you lost all the fluid from the front res. there should be more than a little wet spot. The front res is for the front brakes. You must have a leak somewhere. If there are no obvious wet spots up front check under tha dash. Sometimes master cylinders leak and it comes inside and drips on the carpet, and is not very visible at first. I' had that happen on an old Chrysler I had.

Under the dash is dry. The front brakes are dry. Unfortunately when I refilled the front reservoir, I filled it a little too full and when I replaced the cap, it spilled over, so I can't tell if the proportioning valve is leaking!!!

is it the little reservoir or the big reservoir that was low? if its the little one, and you said the one drum was wet = wheel cylinder

Yeah, it's the little one. This morning I found a couple of wet spots on the garage floor by the rear tires. Looks like fresh brake fluid that I put back in last night, but I can't see exactly where it is coming from. Guess I'll replace both of the rear wheel cylinders and see if that fixes things.

check for leaks or cracked lines first, but its most likely the wheel cylinder. usually, itll sling brake fluid all over the inside of the tire (assuming you have any fluid in there. if you were completely dry in the reservoir at the MC, i would bleed the MC as well as the lines when you replace the wheel cylinder.

I looked at the lines and I couldn't see anywhere where there was an obvious leak. It does bother me somewhat that a couple of the lines are actually rubbing on the shackles and have worn away part of the protective sleeve that goes over the line to some extent. What do you do to prevent this? It is obvious that the sleeves are on the line for a reason!!!

Yeah, wheel cylinder sounds right. As to the lines,I took some rubber fuel hose and slit it length wise and installed with black zip ties. Works teriffic as chafe guard.

I had the same thing happen to mine a year or so ago. It turned out to be a bad brake line. It started out like what you have described. I couldn't find where it was leaking and I kept adding fluid. One evening I put the pedal down and it went all the way to the floor. My line was also worn. It was a combination of rubbing and road salt. Fluid was spurting everywhere and I had to change my pants.

When you replace the wheel cylinders make sure the brake shoes didn't get contaminated w/brake fluid. If they did, replace them.

Glad to be able to provide some entertainment. Looking back I couldn't have made that sound any worse if I tried. Hope your problem is fixed, Dare.
