WHy was it running when you did the calipers?


Did you change out the rear brakes too?

 

I would check the calipers again make sure the slides are greased!! Then if it still does what its doing, then I would replace the proportioning valve!!

 

Engine off
Pump peddle three or four times.
Push peddle to floor and hold.
Open bleeder screw, let bleed for 1-2 seconds, close screw.
Release brake pedal and repeat until all air is out of hte system.
Start with the furthest brake, passengers rear, then drivers rear, passengers front, and finish with drivers front. In that order. Make sure you dont run out of brake fluid, and put the cap on while bleeding. If oyu leave it off all your fluid will spill over thet top and it WILL suck air. 2-3pump/bleed cylces and you should need to top off. Your get the routine down ont eh frist brake.
