I have an 03 Saturn L200 that I change the rear brake pads on and the wheel cylinder. Every time I pump the brakes to bleed them the wheel cylinder pops and brake fluid pours out. I have no clue what's causing the problem. Not sure if I have something wrong or if the wheel cylinders are bad from the parts store. Can someone please help me?

 

 

Astute observation, Dr.

 

yes sir I do bleed them with the drum on. Still bust every time.

 

 

They're NOT assembled correctly. Look at the notch in the wheel cylinder, The brake shoe is NOT seated in the groove. You have nothing to block the pressure of the fluid from popping the cylinder out. Put those shoes in the slots, NOT outside them. Drum brakes are not that difficult if you just pay attention to how they come apart. My Dad taught me to do one side at a time, so you can always use the other side as a reference.

 

You are correct! I took them apart and reassembled them and there perfect! Thanks a lot!

 

 

Happy to help. That's what we're here for.

 

I haven't worked on drum brakes since my buddy taught me how to in high school. I thought it was nasty then and I have succeeded in avoiding them for 30 years running.

Power to ya for fixing em and power to Rube for detecting an issue from a single pic. See Rube .parts of your memories can't be lost no matter how many times they slice your brain 😄
