Hey guys I finally got my new rims installed and they're Dick Cepek DC2 16x10 and after having them mounted and aligned my brake light is now on. I checked the brake fluid and it was indeed low so I refilled it but the light is still on. Is there anything that could have caused this?

 

Check the brake line going to the rear. It likes to rust out, and break. Usually right above the gas tank.......

 

+1 on heyyou's response. if your level was low, it's leaking somewhere, and by the gas tank is common. Check your rear drums for leaks to, the cylinders in there can give up the ghost too and leak.

 

I've checked the lines and all seem good. I've also checked the reservoir after driving it around for a few days and the fluid level hasn't changed.

 

Does your parking brake light stay on as well?

 

No its just the brake light.

 

may have triped the metering valve. lift rear of truck have someone hit brakes and try to turn the wheels by hand i bet the breaks wont engage in the rear
