Trying to figure out what's going on with my front brakes. It started with the brake pedal getting spongy periodically but now there is little to no pressure on the pedal. I have rear brakes but the front won't work. I bleed the brakes but it's still the same. When I press on the brake pedal I can see that the fluid is bubbling up in the front compartment of the reservoir. Also when bleeding the brakes there doesn't seem to be as much fluid coming out of the bleeders on the front. The front driver's side nothing comes out of the bleeder but when I loosen up the brake line at the caliper some does come out. Could it be a clog in the brake lines? Bad master cylinder or the power brake cylinder thing?
Thanks

 

Sounds like your master cylinder is bypassing fluid and needs replacement.

 

It was the master cylinder. Just got it done about half an hour ago.

 

Thanks for posting solution for us.
