WC16534 is the front, and WC16535 is the rear. Rockauto.com in the US is always a good online source for part numbers like these along with great prices to boot. They have the cylinders for $17 to $20, and the master cylinder for just $45.

....For your assistance. I don't suppose anyone has a number for the master cylinder???

Quick question has anyone ever felt that the single chambered piston is inadequate for the braking system and felt the need to change to the dual brake master cylinders conversions offered? i would never want to to disuade anyone from changing something that had to do with safety ...but if it's good and reliable why change it. Mine is rotted out but figured a kit would work to rebuild or replce for the trouble. It's at this point where you ask is it necessary? Any thoughts?

Do it right the first time with all new cylinders and master, along with flex lines, and you should be good for at least a decade. For the price of brand new components these days, why would one bother to rebuild?

My experience is that you have 7 to 10 trouble free years with new, and 3-5 with rebuilt.

Again using Rock auto for an example, you can have the master cylinder and four wheel cylinders all brand new for only $120 plus some minor shipping to the border. Add the four flex lines and the S lines and you will be around the $200 mark. Then you can almost forget about the brake hydraulic system until sometime around 2020.

Of course, this may sound cheap, but of course you are also possibly looking at shoes, maybe drums, for sure wheel seals, and possibly a couple bearings. Don't forget to repack the rear bearings and replace both the inner and outer seal on each side. Chainging the outer only will do nothing. Oh yeah, while you have the front brakes off you may as well do those neglected kingpin bearings: expect to replace all four. The fun just keeps on going and going.
