Thread: Not enough vacuum for brakes?

did you not say you installed f body brakes and the bleeders are on the bottom??? if so the calipers are on the wrong sides, you cant bleed them nipple on the bottom. has to be pointed up.

take them both off, and swap sides, then bleed the brakes again.

mushy pedal is a bad master, a leak, or needs to be bleed, hard pedal is the booster not working. or not getting vacuum.

turn the car off pump the pedal, it gets hard, thats what no vacuum to the booster feels like.

back to this quote then, pull the vac line off the booster, see if you got vacuum on the line, car should stall once it open to air.

OEM brake hose can collapse under a WOT to closed throttle/engine braking transition...say after a burnout....when manifold vac spikes

I seen this before happen on my relatives car. Good thing to check it out. ( Btw: Turbo400SBC Check your messages.)

That's cause under decel the engine pulls more vacuum

hard decal/engine braking = highest manifold vac readings....most likely to cause hose to collapse
