I'm new to all of this I've never taken a smog pump off or deleted the A/c I bought this truck as a project and haven't evits gave it it's first test drive I got it running but the brake pedal is really hard and I have to press hard for it to stop in gear just in the drive way I'd really appreciate all the info and help I could get on all the upcoming work thank you in advance
Go whole hog and wipe out as much of it as you can. Remove the plastic housing the blower motor mounts two, take off the access panel and pull the evaporator too and reinstall it. It will move a lot of air (especially if yours was like mine and plugged up with dirt/debris) OR get a airbox from a non-a/c truck. It will take up much less space in the engine bay (aka easier access to #3 spark plug) and look nicer.
The pipe was plugged on mine before I got it, IIRC the PO used a large bolt in a hose. Come up with something cleaner. I remember I used a non A/C PS belt for the alternator side (so both belts were the same) and it fit perfectly.
Check your vacuum, you may have a leak that is messing with the vacuum booster. Or you may need a booster. Troubleshoot everything, don't just throw parts at it.
