Hi all.
I'm changing the leaky rear wheel cylinders on my '73 delta 88. Rear drums are 11"x2".
Anyone have the GM part # for the wheel cylinders?
or Dorman part #, any others?

Thanks in advance.

 

18004793 w/HD brakes (12 in. brakes). 18004890 exc. HD brakes.

 

I have NO Delco Wheel Cylinders -- for this application -- only very inexpensive aftermarket wheel cylinders (but made in the U.S.A.)!!

and I have a couple last sets of N.O.S. ++ Asbestos ++ Brake Shoes
for this application.....

Call me -- Craig -- 516 - 485 - 1935.....New York -- or if you are outside
the U.S. -- you can contact me through the C.O. website or at
mobileparts@yahoo.com.


Cheers, Craig.............

 

Thanks for the offer Craig. I've managed to source some closer to home.

 

So I spent yesterday swapping out the rear shoes and cylinders as well as installing a new brake spring kit. I cleaned up the backing plates and gave the drums a hit with the wire wheel and a coat of H/Temp black after I had them turned. All the metal parts were plated after a I buffed them to free them from years of grunge.

Trivia time, the adjuster access hole in the bottom of the backing plate has a steel plug in place? It's non-removeable, ie part of the backing plate stamping. Is this common?

I had been putting this job off as I still can't bend or walk on my knee properly after my bike accident 4mths ago and subsequent knee recon.
I'm too lucky to have a few close mates who came around to help. Actually they helped drink beer, eat the bbq and laugh at my attempts at getting down on the garage floor and trying to stand up again.. but we got there in the end.
Not surprising the pedal is most reassuringly firm now and the park brake actually works again...

some pics to share..

I believe that if you want, you may knock that plug out and insert the correct rubber plug. I have seen some of those plugs in metal.
