Continued on from Part 01.
Underneath, there’s a nut to be removed with a 10mm socket or wrench:
On the other side we need a flathead screwdriver:
Lever etc. removed:
That leaves us with the front brake switch assembly underneath – part number 35340-MA5-671 – still seems to be available:
You can see the button that is actuated by the lever movement here:
One screw+washer removed, part number 93893-0401218 or later 93893-0401208:
The brake light switch now lifts out:
Now it’s time to take a look at the internals. With the lever out of the way we can more clearly see the rubber boot around the piston end:
Easiest way to get this off that I have found is to grab as much as you can between your forefinger and thumb (too little and it tears) and lift it off:
Now we can see the end of the piston:
Now look down around the piston from the top and you should see a circlip:
Using some internal circlip pliers, release the circlip. Keep in mind that the piston is compressing a spring, so once the circlip is released the spring will cause the piston/circlip/etc. to push outward. It’s not an incredibly strong spring, but it’s certainly enough to send the circlip off into a dark corner of the garage or under your desk.
The insides:
Look into the bore to check for gunk and corrosion:
The piston and rubber seal:
Spring end:
Pressing against the piston we have a rubber piece that the spring seats into:
The spring end which meets it:
The piston is in better condition than some we have seen:
That’s it apart – next step is to do some cleaning and then make use of the rebuild kit.
