Just thought I'd share. I did my rear drum brakes last weekend... a lot harder than doing disc brakes. Anyway, I heard a scraping noise coming from the rear and after 150K miles thought I should do the brakes. Took off the drums and the brake shoes were only 1/3 worn. My front discs have been doing all the work. Guess that's why I was only getting 15K on my fronts.
Well the brake cylinders were leaking in the back as well. God Bless Chiltons.
I bought 2 new Wagner brake cylinders and new brake drums/shoes from United Motor Parts in Teaneck NJ. Great place. Installed the new parts and shoes. I made sure to buy a brake kit which included all new springs, clips, etc. (highly recommend spending the extra $12 to do so). The kit even had rubber covers for the adjustment slot on the back side of the assembly (which were missing).
After all these years (8) of having dealers and mechanics work on my van, I finally feel the van braking flat. No more nose dive because the front discs were doing all the work.
If you want something done... you have to do it yourself (with the exception of my 15 year old daughter who helped me bleed the system by pressing the brake pedal). I'm sure I saved a heap, too. The whole job came to about $160. Replacing the brake cylinders and a rear drum brake job at a dealership would have set me back at least $400.
