SOURCE: 2003 Volvo - motor stalls when making right turns & applying brake

This sounds like the idle speed control system is full of sludge, have it cleaned.

SOURCE: While heavily applying the brakes at high speed the truck shakes.

If the front of the truck is doing all the shaking then the front brakes are doing all the stoppong. You need to check the rear brakes and change if neccessary. If they do not need to be changed then you should adjust them accordingly. I hope this helps. Don.t forget to rate my answer, thanks.

Are the engine rpms climbing when its jerking forward? seems like it could be a Transmission torque converter problem.

Have a 1995 Buick Regal. Car stalls when braking at a stop sign or braking into a left or right turn.RPMs drop to 500 then stalls without warning.Car starts right up with no problem and runs great.


Do you hear a sucking noise from under the hood when you apply the brakes? You could have a bad brake booster venting too much engine vacuum when applying the brakes causing the engine to die.

Stalling troubleshooting


run fault codes to check for electronic problems (TCM). If this problem only happens when the foot brakes are applied check for brake booster vacuum problem. Remove vacuum line and blank off and apply the brakes to see if the engine stalls at idle.

Stalls at stop light and rush hour traffic


disconnect the vacuum line to the brake booster and plug off to the engine. run the engine and apply the brakes and see if it still cuts out. If not the reattach the vacuum hose and re apply the brakes . If there is a stall then replace the brake booster as there is a fault in it that is allowing air into the manifold on brake application. This problem is not connected to the CPU by sensor so no faults would be recorded.

INTERMITATE ENGINE STALLING FAULT WHEN BRAKING ON


Can you give me some more information? Does it run fine if you do not apply the brakes? This could be a failing brake booster and you are loosing vacuum when the brakes are applied....

At times when brake is applied,engine dies and brake light comes on,and check engine soon light comes on. Engine will start right away,but service eng light stays on


It sounds as if the brake booster is leaking. When you press the brake pedal, vacuum is drawn from the engine supply, if the booster is leaking, it allows too much vacuum to leak, stalling motors & triggering sensors. There is a check valve located between the line that comes from the engine manifold over to the brake booster & that can also cause problems.

Plug that line & use your brakes, if it cures the problem, you've found your issue.

Other than that, if you have another vacuum leak, the use of the brakes could just make it so bad that it then triggers symptoms so you shold check your vacuum lines. Vacuum leaks can be identified by usiing a can of carb. cleaner with a nozzle, spraying a small amount in bursts near vacuum lines, connections, and plugged lines. If there is a leak, the engine will stall or slow when it draws in the carb cleaner and you should be able to identify where the leak is. Go slow, spray only a little at a time & allow it to dissipate as it is a flammable product.

good luck

Engine cuts out intermittently. Traced to brake application, turn signal activation, moving gear shift, opening drivers door. Loose gnd wire??? Can even make it stall by turning on radio or rear window...


An intermittent electrical problem can be maddening to fix. I have a similar problem in my truck. The connection to the engine fuse in the interior fuse block is loose. If I wiggle the fuse to re-establish contact, the engine will restart.

Next time the engine stalls, notice which of the lights illuminate on the dash. Compare this to which lights illuminate when you first turn the switch on and when engine will start. Applying the brakes probably shifts the loose connection enough to cause the engine to stall.

Stalls or wants to turn off when pushing brakes


Check for vacuum leak within power brake servo unit.
Remove vacuum hose from brake servo and block off the open vacuum line from the engine. Check that engine then runs normally when brakes applied.
Do not drive the vehicle with the vacuum servo disconnected, as the brakes may not be effective. - The pedal pressure required to apply the brakes effectively may exceed your capabilities.

If the brake booster servo diaphragm is leaking it will need to be replaced/repaired.

91 XJ6 Stalls occasionally in Drive with brake depressed


Idle valve? If stuck in hot position (they often do), then not enough air when engine is cold. Symptom would be that it does this more when cold. The brake pedal thing gets me a bit, does it do it when the handbrake is pulled on but in Drive? If so, nothing to do with brakes, but just that there is a load on the engine caused by halting the torque converter creep, which goes back to idle control problem. If it is only with the foot brake, then I would suspect vacuum leak, there is a whole host of vacuum circuits on your Jaguar, have a look for hoses that have rubbed on the engine and have a slight hole or ones that have perished. Pressing the brake causes a reduction in vacuum to all the circuits, but if there is an air leak, then this can cause the inlet manifold vacuum to collapse and the engine to stall.
