There is oil leaking under the dashboard of your 89 Toyota Pickup IT leaks under the dashboard to the brake pedal It's power steering oil Please help find the source Thanks?
No, it's brake fluid. The master cylinder is leaking out the back and running into the brake booster. The booster is half full and fluid is coming out and running down the rod that connects to the brake pedal The above answer is the most likely cause, but if you are certain that it is power steering fluid... here's a theory. Some vehicles do use a hydraulic power brake system that is powered off the power steering pump. It is possible that the system could be leaking near the location where the pedal plunger is located, thus allowing the fluid to leak inside the vehicle. Whichever is the cause, you should repair this very soon as it could lead to serious problems with the braking system, and could lead to brake failure. Good luck !
