CTP hydroboost stalling motor.

[Eric Knutsen]

Hi all.
I installed the CTP HB kit.

But when when idling, and I apply the brakes the motors RPM drops and sometimes it stalls.

When driving and brake at slow speeds, I can hear the PS belt slip.

Makes me think the HB is putting a lot of load on the PS pump.

1978 Scout 727 392.

Any thoughts?

I replaced the belt. Now it doesn’t slip. But pumping the brakes pedal still stalls the motor. Also stalls when turning the steering wheel.

My first guess is that you crossed the hoses going into the hydroboost. Are they installed as per our direction sheet? Link to our directions - CPT Scout II Hydroboost Installation Instructions

Or feel free to post a picture of your installation so we can see anything obvious.
