Rear Master Cylinder: reasons to remove exhaust?

Post by LeYak »



Dear Wingers,

since I'm replacing the apparently original 1993 rubber brake lines on the Wing, I thought I'd have a crack at the rear master cylinder while the system is down. So I bought a revision kit and was ready to start dismantling... until I took a look in the repair manual.
Holy Wingbats, that's a serious list of dismantling, especially the exhaust stuff :shock:

Now, I realize that Mother Honda probably has good reasons for this, since they designed the thing (although the placement of the Master cylinder does make me wonder whether they were on 80s LSD while doing it). Now, I've gotten the heat protector off without loosening any exhaust stuff. I figured that was the main reason for loosening the exhaust: to gain access to that back bolt.
However, are there other reasons? Will I have to still get into the exhaust stuff to be able to remove the master cylinder?
This is how I've got it right now:

There have been a couple people who devised shortcuts to get around the massive amount of disassembly required to remove that thing. Here's one of them:

I don't recall the other one, it was a few years ago, but if I remember correctly it involved a bit of bending and force.

Okay, thx for the link. I'm not really comfortable with cutting the metal lines, so that'll be a no-go. But that post did point me to another reason for lowering the collector: to gain access to the front caliper line. Hadn't really realized the difficulty of that yet.
No idea if I'll be able to come up with a creative (non-destructive) solution for that hurdle!

If you do manage to come up with a solution then I will nip over the water and bring mine for you to work on. It would be a shame not to utilise all that knowledge you have acquired.

Hi everyone,

quick update: I tried getting to that front caliper line with a bent wrench, and managed to reach it but lacked the leverage to loosen the bolt and risked severely roundin it. So I decided against it.

And given that the shop manual also indicates that you need to remove the exhausts to remove the exhaust chamber to remove the reverse resistor to be able to remove that 3inch long rubber brake line to be able to replace it with a new one (sheesh, Honda :roll: ), I decided to just get it over with and dig into removing the necessary exhaust parts anyway so I can do both the master cylinder and replace all the soft brake lines in one fell swoop.

So, in all, an unsuccessful experiment, but thanks for the feedback, everyone!

No, it was a successful experiment, in which you determined that alternate methods weren't working.

All of the time that you spent trying to come up with a workaround was longer than just dropping the pipe, so the next guy who reads this can thank you for letting him know.
