Brake question

I just replaced my booster and master cylinder on my 1996 silverado. I bench bled the MC, and I bled the brakes. There’s no more air bubbles in the fluid coming out of any bleeder valve, but my pedal is still spongy. The brakes work, but they are just spongy. Any ideas or tricks that I could try?

Keep bleeding them, you still have air in there somewhere!

you could try to back bleed your brakes.

You have to pull a vacuum on the back brakes to get the air to the bleeder valve. You disconnected it at the highest point and air bubbles will rise. They are a royal pain to get out sometimes.

I used a vacuum pump on all of them. I only pumped out fluid. Will try again tomorrow. Thanks

There usually is a special order to go in, such as back right, front left, front right, back left or such, check on your car, i just made that order up.

strip…strip…FISH ON!

if you have no air in the system, check your rear brake adjustment. you want the shoes to be lightly touching the drums creating a slight drag when rotating.

Could be a severe vacuum leak to the booster, or an ABS system failure, if you’ve bled them properly?

I believe you are right Fracwilt. I took the rear drums off today and the rear brakes are non existent. I will replace them this weekend and see if that fixes it.
