Alternative rear MC push-rod
« on: June 26, 2018, 03:14:04 AM »
Just finished rebuilding a complete set of brakes to replace the tired, butt dragging 32 year old originals on my R. All the zinc was gone from the push-rod I was going to use & there discontinued so after talking to @hawaiiysr he steered me toward Suzuki. We have an 87 LT230 & it looked to be pretty close so I ordered one for that. I think the LT250 & Zilla also used the same rear push-rod in the same era so one could be ordered for any one of those LT's & it will work on the R rear master. The part number for the one I got was 69670-00A00. Above the seal groove all the dimensions are within a few thousandths so there a direct replacement. I used a Shindy rebuild kit for the R master with the LT push-rod & it fit together like it was OEM. The LT rod is about 1/4" longer than the Honda rod so it will probably need to be shortened to keep the brake pedal in the right spot with OEM pegs & pedal... Also for the front master cylinder there was a kit shown specifically for the 86 & than a kit for the 87-89. The 86 kit was in the $35-40 range but I got the $18 87-89 kit anyway & it was identical in every way to the guts I pulled from the 86 front master I used for the rebuild:

Interesting, I made a billet clevis, and needed to shorten the pushrod, and add to the threaded area for the aluminum clevis. While off, I painted the pushrod with the same Sunrise Red Rustoleum paint used on most of the other parts of my "R" Didn't see much if any damage.

As long as you didn't paint your push-rod above the seal groove you will be ok for awhile.

I fail to see a reason, The pushrod is not in the fluid chamber, the flexible rubber seal at the bottom is only there to keep out crap, so it has no purpose other, to push the piston. I painted the pushrod completely except where I put a small amount of grease in the area where it touches the piston to keep it from squealing
