My wifes car her brakes are getting low i have checked the fluid it is ok to the line i do not see any leaking around any of the wheels , Is the master cylinder leaking and what is the procedure to check this. Any help woud be appreciated. Thanks, John
Just because you don't see fluid on the backing plates don't think for a second that the wheel cylinders might not be the problem. Excess brake dust can absorb the fluid leaving a slimy mess and fool you into thinking that everything is honky dory inside the drum..... WRONG Pull the drums and visually inspect before ruling out the wheel cylinders as the culprit. Master cylinders USUALLY leak out the back around the piston shaft seal, fluid can usually be spotted running down the brake booster where the master cylinder is bolted in place Have fun with the brakes

How much pad and shoe is left on all 4 corners? As the pads wear and shoes wear the fluid level naturally drops. You might not have a fluid leak at all and just have low pads and shoes.
