I have a '06 Nissan Xterra, built off of a truck platform and shares many of the same components with the Frontier. What do you think the brake bias is, front to back, when I press the brake pedal? In other words, when I press the brake pedal, what percentage of the stopping power is performed by the rear vs. the front?
 
Back in the days, the NJ inspection stations would have a gizmo to check the brakes. The inspector would drive the vehicle about 15 feet and step on the brakes hard. They had a fluid level (like they measure blood pressure) for each wheel.

That was in the 1960s. They also checked headlight alignment with another gizmo.
 
I loved VW's old headlight alignment "computer". It would give the read out and then the customer would have it adjusted and then later get the tire pressure adjusted. (Altering the align).
 
may be variable. i had a 97 p'finder at the bias valve had an arm that reached down to the axle. the heavier the load, the more the rear received.

The Westfield Inspection Station still has that (former) apparatus, even though they do not even look at it after the test.

The last time I've seen them use the (latter) headlight level/alignment device was at least 15 years ago.
 
And when your 10 a trip to the inspection station was fun. Now its annoying and sometimes costly.

My mother grew up in Westfield and her Dad walked to the train every day then into the city.
