Topic: drinks brake fluid... suggestions?

[87hillbillyoter]

hey all-

the e-brake light was comin on last week so i searched and found out that meant brake fluid was low. i didnt think much of it and filled it up. the light went off. now, the master cylinder was back to its spot below min. so i just filled it up again. any idea what this could be?
thanks in advance.

From the sounds of it, you have a leak in one of your brake lines. Check the lines above the fuel tank, that is usually the spot that rots out. It is very common on yotas for this to happen. I just replaced both lines for the same reason on my 4runner.

Ya look for a leak. if you cant spot one right away, fill the res and use a rod or stick to push the pedal down and then go look for a leak. Not in your case but sometimes when the light comes on it means you need new brake pads because the pistons of the caliber now are sticking out a lot do to the pads being worn down. So if you full the res and then put new pads on it over flows the res. Cuz you push the pistons back into the caliper.

  see if you floor board is wet, or slide the dust cover on your slave cylender back it should not be wet. or full of break fluid

just trace all the lines out and check your calipers and brake cylinders for leaks.

wheel cylinders in the rear drums. very easy to replace and are usually the first things to start leaking.

thanks guys. figured out its a leak in the RF caliper. does this mean i need a new caliper? im not too familiar with the brakes on these trucks

I would go with new caliper.  You can get a rebuild kit I believe, but I've had bad luck with rebuilding myself.  The new one is less work for a little extra money and I believe you will get the core back on the old one.

Flush the system out good to get any crap out that might tear up those o-rings and boots.

yup, just get yourself a new one!

Like yota said, wheel cyl's are notorious for leaking.
