Question about Toyota 4Runner
Well if you don't have a leak in the brakes hydraulic system then I would say you either have a broken/disconnected power brake booster vacumn line(booster is mounted to the rear of the master cylinder pie like disk shape), a bad power brake booster
Immediatley have this cars brake ABS system computer scanned for codes to find out what the ABS light being on is about, that is usually due to a broken wheel sensor, but a code scan will reveal the truth.
So in reality you have a two part problem, as long as you have a full master cylinder revealing no leaks, which are: 1) brake booster/defunct or vac. line problem. 2) ABS system scan for wheel sensor or the like.
Hope this Works!!!
