Still don't know how to test the trailer brake without Hand Valve.

i cannot see any other way to check'em with out that hand valve.

getting back to buying the part, see if you can buy it AT the DEALERSHIP, so this way you will have a factory OEM part. i would NOT suggest a bone yard, all for "insurance sakes", then inquire at the stealership how much to install the part you just bought FROM THEM.

since you are about to buy this truck, tell them to do it for NO CHARGE...see how they respond to this, if they want your business they may do it for free or at the very least, a REDUCED PRICE...

 

I think we missed it folks, I just looked at how they hook that up at the engineering drafting stage and doing a tug-test makes sense at first glance and a tug-test will check some things but we are lacking a few details and if OP really wants to go to the effort to put enough $cratch to buy any truck then hiring some local shop to do what he asks starts to make a lot of sense -> what if he does what we say and 100 miles later there is a brake failure on the trailer - we in screwed-pooch-city at that point, anyone with enough money to buy and sell trucks can go hire an actual mechanic

 

i didn't "miss out" on anything....i've been telling it like it is all along...

 

Back up real fast and slam on the brakes, hahaha! this is how you automatically adjust the brakes. Then get under and check your slack adjusters, and inspect your brake shoes and housing for cracks or wear, that's what I'd do.

 

get out and look at the brakes. if they are out of adjustment. then adjust them.

not ONCE have i ever tugged on the trailer. and it's YOUR job to inspect the trailer.

if the brakes are out of adjustmnet. that's a sign the automatics aren't working. OR some other problem.

 

From my driving experiences and most trucks I've driven on a regular basis not having a hand valve, I can tell you that you quickly develop a feel for the brakes (including the trailer) on a rolling brake test by using only the foot pedal. A hand valve is not really necessary unless the driver has become so accustomed to using one that he'll have it no other way.

 

I'm still waiting for all the swift and prime drivers to speak up.

I believe they know the correct response to this problem....
