Have bled the brakes twice...brakes still feel spongy and have to press brake pedal down all the way to get vehicle to stop but only in the mornings...in the afternoon or after the vehicle warms up the brakes are ok. Any suggestions greatly appreciated!!

 

some more information about your Jeep would be helpful....


You could have bad brake lines or brake booster.

Are you loosing/leaking any brake fluid?

 

Thanks for your reply...no leakage of brake fluid noted.

 

How are you bleeding them? Using a vacuum pump?

 

Both...with vacuum pump and manually.

 

Have you done any brake work before the low pedal issue started?

 

JMHO, but I think you need to PRESSURE bleed the ABS system to make sure there is no air in it.

 

Thanks everyone for all your replies and suggestions. A new brake master cylinder did the trick.
