Why not bench bleed on truck?

[ubtripn]

Couldn't I use the plastic nuts and route the tubes to the reservoir but mount it (not hook up the brake lines) then use the pedal to bleed it? Just curious.

Yes you can. I've done it several times.

[ubtripn]

Awesome, thank you! I am replacing - again - the mc but one with the booster attached. It shows four bolts and am assuming the install should not be too hard.

[ubtripn]

Do I have to go under the dash with the booster replacement?

You don't even need to bench bleed if you can lift the rear wheels a bit until the reservoir is closer to level. Bench bleeding is only required, so far as I am concerned, on vehicles with really steep reservoir angles.

If you do bench bleed with those plastic fittings, be sure to release the master cylinder slowly after pushing the piston in. If you release too quickly and those plastic fittings don't have a good seal air will get sucked in past them. Pissed me off royally that it kept blowing bubbles out forever until I figured that was why.

Great point, that happened to me too.

Also,given the angle don't you mean lifting the front of the truck to level out the MC?

Perhaps this is true if you want to gravity bleed the system. But bench bleeding on the truck is so easy. Why not just do it?
