Was coming down a 6 mile long 6 percent grade today and doing like I normally do: slow to 45mph at the top of the hill, activate the engine brake, and proceed, ocassionally tapping the brake pedal if speed increases beyond 45mph.
This seemed work normally, until several similar grades later, and I noticed the ABS light come on.
I then noticed restricted accelleration at take off /ramp up speeds. Also in monitoring TPS and temp, the inside dual on the passenger side began to warm up and showed eventually 25 lbs of in increased pressure 129 psi and temps in the 130 ยบ range which is almost 20 higher than typical.
As an aside, we joined a 10 mile procession of slow/no go traffic at some point in our decent which inched along for almost an hour. Engine and tranmission temps remained normal.
When stopping for the day, I released some pressure from the tire-- down to the normal run temp of the others.
I have read that if the ABS is malfunctioning the system will revert to normal braking which I prefer, but doesn't seem to have been the case today.
More mountainous terrain for 40 miles tomorrow. Any thoughts on what I could check since I'm in a small town, why this condition might have occurred, and how to avoid it in the future.
P. S, new brakes, rotors and tires just installed about 400 miles ago.
Thanks for your help.
