My truck now has 205,000 miles. To bring everyone up to date about 20,000 miles I had new rotors on the front installed as part of my brake job and have maintained this truck well. Now when I start off and put in the clutch and depress the brake pedal at the same time for the first time since start up, the brake pedal continues to depress and I have no brakes. Then the brake will be fine like the system pumped up? I checked the brake res and it's ok. Any thoughts? Thanks.

 

flush the powersteering fluid first, as the fluid gets trashed easily as its overworked suporting both brakes and powersteering, its usually never maintained,

failing that, your hydroboost might be on its way out, there are some tests that can be done easily to confirm its operation
