I think I jinxed myself. Hadn't had time to be on here for awhile. Logged in today and later on I lost my brakes. Turns out I must have a leak in the rear brake circuit.
I got the brakes bled and the brake light off but now it feels like there is a brick under the brake pedal. It is extremely stiff after a couple of inches of travel. Brake performance is very marginal. I can barely skid 1 rear tire with a lot of force on the pedal. If you pump the brakes a few times with the engine off, you can hear the vacuum booster bleeding off. If you start the engine while lightly pressing on the pedal, you can feel the pedal drop as the vacuum increases.
Brakes were bled farthest to nearest. Vacuum was measured at idle and around 1500 rpm. Vacuum max is. 16 inches. Without the soup can vacuum canister on the drivers side, the brakes bleed the vacuum down about 5 inches with each press of the pedal with the engine idling. With the canister it is about 1 inch. Vacuum holds at 16 once engine is turned off.
Any thoughts on this? Could something have been damaged when the rear circuit was ran out of fluid and I had to use what brakes were left to get the truck stopped? Is there something in the brake warning switch that needs to be reset? I thought bleeding it was how you reset that switch. It is an 86 so I am not aware of any RABS on it
Thank you for your thoughts on this.
