Yesterday I noticed a popping sound from the right rear while braking. Got the drum off today, turns out one of the cylinder pistons has a bad seal (see the pictures), so I'll need a replacement. I couldn't fine an OEM part number (can anyone help with that?) But here are some brands that make replacements:
- Brakeware (at AutoZone)
O'Riley's house brand
Napa
Altrom (also at Napa)
Also, is it best to replace both rear cylinders at the same time? Haven't done this before so all tips are appreciated!
Thanks!
