Brake fluid problem
About 5 months ago I had an issue where everytime i would stop hard or go around a corner my brake fluid light would come on. I thought it was wierd but just filled it up and had no issues with it again, until now. It was doing the same thing as before so i bought brake fluid and filled it up. Next day it starts doing it again so I look for spots under the car and any leak anywhere and cant seem to see anything. But about everyday I have to fill the brake fluid. Anyone have any ideas??

Check ur calipers for leaks also when doing this bleed ur system. If ur calipers are dry and all the air is out of ur system the clutch is also using the same res

stop by your local auto parts store and tell them to order you a couple caliper rebuild kits. each kit is only about 8 dollars.
The rebuild kit comes with a new square cut seal, dust boot, and snap ring.
remove the brake line from the caliper and plug it.
remove the e-brake cable
remove the caliper and drain it
remove the caliper slide bracket
remove the dust boot and piston, then remove the sqare cut seal from the piston
thoroughly clean the piston and cylinder
replace the square cut seal on the piston
lubricate seal and cylinder with brake fluid and reinstall the piston
install the new snap ring inside the dust boot and use a mallet to tap on the new dust boot.
reassemble
...or you can spend hundreds on new calipers.
There are several things that can cause a caliper to leak:
-overheating detroys the square cut seal
-old broken down brake fluid does not lubricate as well, and will cause excessive wear on the square cut seal
-contaminated brake fluid can scratch the cylinder walls and destroy the square cut seal
-a torn dust boot can allow contaminants into the cylinder causing scratches on the cylinder wall and destroying the square cut seal
When rebuilding your calipers, inspect the bore to make sure the inner surface is not scratched. If it is, then you will need new a new caliper, and you can return the rebuild kit.
