7.3 OBS brake booster adjustment with test drive! TSTG Episode 3 

I've fixed the issue!!! It ended up being a bad vacuum pump! I will go over what I did to trouble shoot the issue in my next video!

My abs light turned on drives me crazy seeing it on thanks brother I’m going to try this in mourning

After changing my break booster now my truck runs funky I’ve already changed the break line switch as well.. When accelerating it feels like the break never stop I let off the gas pedal and it stops as if I was pressing on the breaks.. note: at times it runs normal would I have to adjust that rod?? Plz help if you can my family business is counting on it

👍👍👍 now I have a base on where to keep looking, I changed out the vacuum pump (2nd time), and it helped with my AC but now my brake pedal goes straight to the floor

Also, just found your channel today. Liking you videos keep it up, good job.

Another thing you can do is purchase a master cylinder for same year truck but for a fsuperduty model u half to slightly oblong the mounting holes but it bolts right in and is a huge improvement for braking power

Hey bro get the recall done on the switch on your master cylinder. Lots of trucks burned down cause of it!

had the same problem on my 96. New master cylinder and bled the hell out of the brakes. Still long and soft pedal. Replaced the ABS unit and bled the brakes. Fixed the problem. The seals go bad in the unit and causes the pressure to bypass

i have a 97 obs 7.3 non intercooled that has a soft pedal. has new master cylinder and fluid. have to pump the pedal 2-4 times to get a decent pedal. any ideas? has 130k miles

I have to rebuild my zf-5 but I’m thinking of doing the hydro-boost upgrade. Taking the hydro-boost system from a newer powerstroke on my 94IDI.

Are your rear drums correctly adjusted? It's ridiculous the difference it makes if those rears aren't adjusted right. The only real way to tell is to put the truck on stands with both rears off the ground, then adjust them till you just can't turn them by hand, then back them off just a little til you can turn them by hand again. Believe me, it makes a big difference. Another nice upgrade option is to swap on a hydroboost system from a SD truck, eliminating the vacuum assist system altogether. Just another option...

I am always on look out for good degreaser. My SD 7.3 has had bad power steering leak for years, caked up and finally got redhead steering box and new lines. I will give h7 try!

Your truck is clean.

I have a 2000 Ford 7.3 powerstroke my problem is my break feels like a brick so hard to push down it doesn't stop on a dime at all it's Coast to a stop been at the dealer for 5 days they still haven't figured out what's wrong with my brakes they replace the brake assist still the same problem they say it's a internal fault to something like that

Where is your crankcase breather routed?

What steps do you have on that truck?

Can you link the trans cooler you’re running and the other components to make it work in the truck? I want to mount mine in the same location

I like your videos! I got a '97 turbo duelly, I was watching your vaccum guage and I don't think you got enough?? Mine holds around 12lbs. normal/idle and 20 driving? All new vac.pump!

Being that I’m 2wd also what size tires are you running and what size wheels?

To adjust drum brakes is easy. With truck back on all tires. Reverse the truck with some speed and slam on the brakes. It will tighten them everytime.

I'm currently in the process of building my 96, anyway you could make a video or tell me everything you did/ had to do to make that kind of hp.. love the truck man!

I wish mine was a PowerStroke 😥

Nice

Tip: Your muffler bearing will sometimes require a little spark plug fluid to actuate the camshaft wrist pins.

Mine is an idi

Definitely replace the ABS module bub it'll help alot
