how do you bleed vacuum boost brake system?
Tire pressure is different from one size to another.It also may be different in pressure due to the weather and or driving conditions.You should check with your owners manual.Some vehicles give this info right on the drivers' door itself on an 'inspection plate' The answer you are lookin for can oly be found by yourself by researching.
Try looking on the drivers door frame. It should be listed there. I would take a guess at 50 lbs in the front and 80 in the rear. However if you are mostly driving with and empty box (no Load) then try 50 front and 50 rear. But remember to re-inflate when you have a load on.
Same way you do any other system.
Just like a non-power brake system - you just need to have the engine running while you do it.
A little involved for this forum. Links below will give you a complete education. The actual booster is connected to a master cylinder. You bleed the master cylinder to brake caliper/piston part. 99% of power brakes in the US are vacuum boost systems.
