When you apply the brakes, the vehicle's speed decreases, which in turn reduces the engine load. As the engine encounters less resistance, its RPMs drop because the throttle is often reduced to maintain speed or decelerate. Additionally, the braking system creates drag, causing the engine to work less efficiently, leading to a further drop in RPMs. This is a normal response in vehicles, especially in automatic transmissions where the engine adjusts to changes in speed and load.
What else can I help you with?
When you apply the brakes harder the tach drops like its going to stall what could make the rpms drop by pushing the brake a lil harder?
it may be a bad torque converter.
What causes the back of the car to drop down when applying the brakes?
the rear brakes are grabbing. the linings may have fluid on them from wheel cylinder leak or dust buildup. sanding the shoes may help .
What causes my Jeep Grand Cherokee's engine to surge when idling?
If by surge you mean the batterys volts drop and the engines rpms drop all the vehicles accessories that are on at the time are wanting to draw more amps then the vehicles alternator has to give. or by surge you mean the rpms increase a little bit and if the heat or A/C is on at the same time the A/C pump or clutch might possibly be going out.
What are the advantages of drop bar brakes compared to other types of brakes?
Drop bar brakes, such as caliper brakes or disc brakes, offer advantages like improved aerodynamics, better hand positioning for control, and increased braking power compared to other types of brakes like cantilever brakes or V-brakes.
What would cause a rise and fall of RPM while idling in gear?
the rpms should rise and then drop no more then 500 rpms when the fan on the radiator turns on and then off.
Your 1992 voyager does not seem to drop into proper rpms so im 5000 rpm and 65 mph?
If your 1992 Voyager does not seem to drop into the proper RPMs so that you are running at 5000 RPMs at 65 miles per hour, the timing belt might need adjusted. It can also indicate the idle is set too high.
What if your 1994 Cadillac eldorado with a 4.6 northstar dies everytime the rpms drop?
Try replacing the map sensor
What happens if you go too fast in first gear?

What would cause your brake light and abs light to come on but not all the time on a 2002 chevy silverado 2x4?

Why does a 1983 Monte Carlo with 305 eng loose RPMs when the air conditioner comes on?
The A/C puts an extra load on the engine, so it's natural that the engine RPMs drop slightly when the A/C is activated.
What could be causing my 2001 suburban to drag at low RPM almost idle When I slow down and begin to come to a stop the RPMs drop and the voltmeter falls below 9?
is it an auto? it sounds like if its an auto that the troque converter clutch is sticking and acting like a clutch in a manual trans when this happens its like never pushing in the clutch till the last second which causes it to nearly stall hence the drop in rpms and voltmeter readings as the battery attempts to keep motor running
What causes the drop of a wall cloud?
A wall cloud marks an area of low pressure within a mesocyclone. The pressure drop causes a temperature drop, which in turn causes water vapr to condense.
