First off, when you say dump truck, I'm going to assume that you're talking about a heavy duty Class 7 or Class 8 truck, since that's kinda my gig, even though I'm well aware that dump trucks can be anything from a 1 ton pickup and up.
The first question I'd ask is whether or not you're downshifting when you're supposed to. If you're letting the RPMs drop too low, that's going to bog your engine down. Aside from that, year, make, and model are important to know here. The reason being that, while older trucks will use a linkage from the accelerator pedal, the accelerator pedals in current production trucks are basically electronic switches, and, depending on which yours has, you could either have a linkage which is seizing and not responding in a timely manner when you let off the accelerator to press the brake pedal, or, in the case of the electronic switch, there may be an electrical issue which is causing it not to respond immediately, which would leave the accelerator applied while you're hitting the brake. This is just a shot in the dark... we'd really need hands-on diagnosis to determine for sure what the cause is, because there are a few different reasons why this could be happening.
What else can I help you with?
What is one example of negative acceleration?
A car slowing down when the brakes are applied.
What happens to the speed of a motor car when brakes are gently applied?
The speed of the motor vehicle is gently slowed down. The more aggressive the brakes are applied the faster the vehicle slows down eventually coming to a full stop.
The front end of 1995 Toyota tocoma 4wd is shaking Tires rotated and good brakes Starts at 65 mph and get worse as you try to slow down?
If it shakes only when the brakes are applied, its the brakes. Just because they are "good" and stop the truck well doesn't mean they are balanced and wont cause a vibration.
Abs brakes in back on 94 Chevrolet s10?
The abs brakes on the back of a 94 S10 are designed to help slow the truck down quickly. Without abs, the brakes can lock up and the truck could slide uncontrollably.
What does a master cylnder do?
It holds the majority of brake fluid and pushes it down the lines when brakes are applied.
Why does your accord jerk when slowing down?
if the car jerks when the brakes are applied it is likely that the brake rotors are warped
Why tail lights go off when brakes are applied?
to warn the drivers behind your automobile that you are slowing down
You have a 97 Ford F-150 When the brakes applied there's thump when it slows down to about 20mph its consistent worn brakes the cause or other?
worn brakes could be the cause or check the A frame bushings
How are breaks applied in jet engines?
A jet engine has no brakes. Though they do have thrust reversers which change the direction of thrust to slow the aircraft down. Aeroplanes have brakes on the wheels.
Which force stops a train when the brakes are applied?
Friction between the brake pads and the train wheels is the force that ultimately stops the train when the brakes are applied. The brake pads create friction by pressing against the rotating wheels, converting the kinetic energy of the train into heat energy as they slow down the train.
When does a train's brakes start exerting force on the train's wheels?
A train's brakes start exerting force on the wheels when the brake system is activated by the engineer using either compressed air (pneumatic brakes) or electricity (electric brakes). The force applied by the brakes creates friction between the brake pads and the wheels, which slows down the train.
How does the use of car brakes reduce friction?
When car brakes are applied, they create friction between the brake pads and the wheels. This friction slows down the wheels, reducing the car's speed.
