Sounds like a Vacuum leak in brake booster.
Yes, brake servo failure can be intermittent. This may occur due to a vacuum leak, electrical issues, or inconsistent operation of the servo itself. Symptoms might include fluctuating brake pedal feel or varying levels of assistance when braking. An intermittent failure can make diagnosis challenging, as the issue may not always be present during inspection.
If the engine is cutting out when you press the brake pedal This is indicating a servo or vacuum leak to the servo which will weaken the air/fuel mixture to the extent that the car will not run I hope this post is of use to you best wishes
brake leakage? or vacuum assisted vacuum leak?
Most likely, this sound is coming from a vacuum leak in your brake servo, or brake booster. Which are usually located on the firewall, the wall that divides your engine compartment and cab.
Check for vacuum leak at brake booster
If the vacuum leak is small, then yes the brake booster will still function well enough to assist the braking action. However, if the vacuum leak is very large, or if the brake booster rubber diaphragm is ruptured , then the brake booster will be inoperative and you will NOT have power assist to the brakes. It's wise to just replace the power brake booster with a new unit if there is an internal leak in it, to avoid an accident due to a loss of braking power.
You can identify a vacuum leak in your brake booster by listening for a hissing sound around the booster area while the engine is running. A hard brake pedal that requires more effort to press can also indicate a leak, as the booster isn't providing the necessary assistance. Additionally, checking for a drop in engine RPMs when the brake pedal is pressed can signal a vacuum leak. If you suspect a leak, visually inspect the vacuum lines and connections for any signs of damage or disconnection.
The power brake booster has a massive vacuum leak.
who ever said that a dodge ram diesel does not have a servo it is not true. I have a dodge diesel 2001 and it has a servo and the answer to this question is it had a vacuum leak in the servo vacuum line, changed that and cruise control worked great. the servo is under the drivers side battery.
