37337 1-ton wheel cylinder install with pics!

I changed my rear wheel cylinders out yesterday since I had the day off for school. Since I had the camera on hand I snapped some shots to let other members see how easy it is.
I bet there are a few people that have read about these and thought, "that might be too hard for me" when in fact it couldn't be farther from the truth.

You will need atleast the following:
  • 10 mm tubing wrench
  • brake tool
  • BFH and LFH (big F#$@ing hammer and its smaller counterpart)
  • slip pliers
  • 3/8" ratchet with 1/2" socket and 3" ext.

Here they are (angelic music playing softly as I stare at them) Napa 37337 one tone wheel cylinders. They cost 8.97 a piece and like a fine Italian sports car, "Made in Italy"





First, remove wheel, this was easy,but I don't live in the rust belt



Second, remove drum



Third, you only have to remove the forward spring to get the wheel cylinder out



I didn't get a picture of the removal of the wheel cylinder, pretty easy two 1/2" bolts and she comes right out.

Fourth, compare the two and they are dimensional close





Lastly, reinstall and bleed the system.

Note: your brake warning light may come on after the job is done ie. after the final bleed ( do not let the system go dry or it is a biotch to get the air out of the ABS unit, read: trip to dealer). If the light comes on, unhook both batteries for 10 minutes and problem solved. Pull out into the street and while backing up apply the brakes quit and hard to re-adjust the rear shoes. Enjoy new found braking confidence.
