hard brake pedal

Is it the vacuum pump. Red brake light flashed on dash. No burst lines or leaking brake fluid. Any help appreciated.

vacuum pump...easy fix...just remember to put the bolts in their proper holes before you reinstall the pulley...not a hard job...I did mine last spring...get a vacuum gauge and check for vacuum before you buy a pump just to avoid replacing good parts...hth


edit to add: when running put heater slider to "heat"...if it only has "defrost" then for sure vacuum pump...the blener doors are vacuum actuated...

Swapped out the vacuum pump. Brakes are good as new.
