ne 1 no about a loud clicking noise from one of the back tires. Also, I noticed this around the same time my pedal went low. I am slowly losing brake fluid.

Well I think you explained the problem yourself? If your pedal is low, check your fluid, if the fluid is low, check your lines?

lines were checked and one was replaced 2 weeks ago. No signs of leak not even from the master cylinder. just slowly losing fluid. Also, the clicking occurs when driving but goes away when you apply the brakes.

Need to check over the work you have had done. Sounds like to me whomever did the work did not bleed the brake system or left a caliper bleeder opened. Although considering you have some brake power that make not be the issue but there is most definitely a problem withe clicking and low level of fluid. I say fill the reservoir and bleed the brakes.

That is the problem. Mieneke has checked the brakes and cant figure it out. They say when they bleed them it seems like air just gets back in the system just minutes later. Like an open end. No luck finding any open ends though. The pedal is very soft but when it nears the floor it is rock hard and stops the car. I believe the clicking may be pad rattle.

Those guys at Meineke sound like amateurs. I'd pull the wheels and inspect the calipers for leakage. Check the brake hoses and lines. Check for leaks around the ABS. Look around the master cylinder and fluid reservoir too. It could be leaking inside your brake booster, so you won't even see the leak, until it's too late and your brake booster as well as your MC need replacement. Remove the cylinder from the booster and run your finger along where the piston enters the cylinder. It should be dry. If air is getting in, that means fluid is going out. It ain't magic, it's just a matter of finding it.

I found that crazyass magic leak. WTF how does a group of so called professionals overlook a broken caliper? My left rear caliper is leaking. That would explain the low brake pedal and the clanking. (a sticky piston) Took me and a couple of hicks at napa to figure that one out. How should I fix this? repair or replace??

It seems like awful fundamental stuff for a mechanic to miss doesn't it :eek: ...... You'll probably be better advised to replace (get rebuilt ones from your supplier) calipers (& pads if needed) on both rear wheels at the same time rather than just repair the faulty one side..... you'll end up spending a few more bucks but won't have to deal with rear brakes for a long long time.....
Cheers,

also check the parking brake shoes... A very often neglected part, but also inexpensive to fix while you have the calipers off. Just for giggles I would replace the brake hoses front and rear. I would certainly not trust any work done by those Bozos!!!
