What to do if there is no vacuum in the brake system?
If vacuum is present in the system, light application will produce less and less pedal travel. If there is no vacuum, air is leaking into the system. With the engine OFF, pump the brake pedal until the supply vacuum is entirely gone. Put light, steady pressure on the brake pedal. Start the engine and let it idle.
What happens when the brake booster is failing?
When the brake booster is failing it can draw excess vacuum from the engine. This occurs when the diaphragm inside the brake booster fails and allows air to bypass the seal. The brakes are then pressed, the engine feels like it will stall, and the idle can drop.
What are the most common brake system issues?

Also please check out the statistics and reliability analysis of Nissan Pathfinder based on all problems reported for the Pathfinder. The electric cooling fan bearings failed at 62,000 miles. The Nissan dealership that diagnosed the problem stated that it is common for this vehicle to experience this part failure.
Why did my Nissan Pathfinder overshoot an intersection?
At that point it was braking but not as efficiently as it should. The inefficiency of the brakes would have caused me to overshoot the stopping point of the intersection. Rather than stop in the middle of the intersection, I applied the accelerator to get through the intersection.
Why is my brake caliper not working properly?

What causes a turbo to fail on a Cummins?
Typically, we see two common issues with the VGT on the Cummins engine; either your steel ring inside the turbo gets stuck or the actuator fails and cannot communicate with the computer anymore. This can cause any number of issues on your Cummins but the most common thing we hear is that the customer is having an issue with their exhaust brake.
What happens when you lose the exhaust brake on a Cummins?
Either a sudden loss of their exhaust brake or their exhaust brake will stay activated even when accelerating.
