Question about 1986 Ford F 250
I have an '86 Ford F250 diesel. The brakes fail after being either consistently used in heavy traffic or on a steep grade, ie mountainous grades. The master cylinder was replaced and it happened again. I was pulling a trailer at the time and had an accident. My favorite mechanic checked out the master cylinder and bled the brakes. The problem seemed fixed until I took her down a steep mountainous grade this week. By midway down the steep grade I could smell something hot and the pedal was going all the way to the floor. I stopped for an half hour. The system cooled off and the brakes were once again fine. Any ideas? Juniper
You are boiling the brake fluid and hence the sinking pedal, go to silicone based synthetic fluid, it will not boil, all the old fluid must be flushed from the system before installing this fluid, this should cure your problem for good.
