I have a 1994 Camry, 2.2 L, 4 cylinder engine. I noticed a few days
back that my brake fluid level was low. I purchased DOT3 FMVSS no. 116
grade brake fluid. Then immediately (after about a day) after some
time my brake fluid level indicator showed the level was low. I kept
refilling the brake fluid without any signs of brake fluid leak under
the car. Someone at Autozone suggested that it could be internal brake
fluid leak. What is your opinion on this?? Any idea how much could it
cost to plug the problem?
Like others said, it can be the master cylinder leaking into the cabin
or into the brake booster (which you won't be able to see unless you
pull the MC). Wheel cylinder leaks will show up if you pull the drum
or look on the inside of the rear wheels if you leaked that much you
should be able to see it there.
If you need to change out the MC, it's also time to consider
rebuilding or putting rebuilt calipers/wheel cylinders and brake hoses
on there. Your local NAPA should be able to help or check
rockauto.com. I personally use Raybestos hydraulic parts and Akebono
ceramic brake pads.
