I decided to save myself some money and do my own brake job. I consider myself handy, but when things go sideways I panic. Now I'm having a problem that I need some help with. My truck is a 16 SCrew, 4x4, with electronic parking brake. I got the front done and buttoned up, but the back is giving me problems. The pistons came out of the calipers, passenger side all the way and the brake fluid dumped all over the floor (what seemed like 1/2 cup of it). Driver side the piston is out about 40-50% and won't depress back in. I ran out to buy a piston compression tool and even that isn't pressing the driver side.

The passenger side, the boot is now ripped, and I am feeling defeated because I can't the piston back in. I have tried screwing the e-break back in all the way to the bottom and then tried putting the piston in... and I tried putting the e-break into the piston and spinning them both together back down, but the piston goes about 15-20% in and the e-break piston will spin down the thread, but the piston itself won't go any further, it'll just spin and spin. I even opened up the bleeder screw to get more fluid out, or to allow for it to go somewhere as I push it back in, and still nothing.

Help! I have to work tomorrow and have no truck!

 

Based on your issues, I would recommend buying rebuilt calipers from the local parts store and call it a day.

 

This. So you don't drive yourself crazy. Next time just use a C-clamp against the old brake pad to depress the pistons.

 

WARNING: Service actions on vehicles equipped with electronic parking brakes may cause unexpected parking brake application, which could result in injury to hands or fingers. Put the electronic parking brake system into service mode prior to servicing or removing rear brake components. Failure to follow this instruction may result in serious personal injury.

 

Didn't know about maintenance mode until after the fact.

 

And now these are saved for when I need to work on the rear brakes. Thanks!

 

Just checked Advance Auto, Autozone, and NAPA, and it seems like they're all w/o electronic parking brake.

 

And to top it off, now you have to bleed the brake system because you opened up the bleed screw.

 

Sometimes Its worth it to let the professionals do it!!!
