The following article was prepared and written by Warchild ( Dale )..
He has done all the manual work, the photography and the write up which
has made the job easy to understand and to follow.
Whilst preparing to install some new brake pads and Spiegler lines, I
thought I'd get off my lazy arse and actually disassemble my woefully
neglected callipers to thoroughly clean and inspect. I probably should have
gone ahead and replaced seals and all, but just forcing myself to
clean/inspect was a feat by itself!
Right, off we go, then.....
First, you take your MityVac and suck out every trace of old, nasty brake
fluid from the brake system as clearly outlined in Chap 15 of your Honda
Blackbird Service Manual. Before you crack open your first bleed nipple, suck
out the master cylinder until it's bone-dry:
Here is my neglected, nasty-ass crusty left front caliper:
Close-up of the pistons all caked with road splooge from 60,000+ miles of use.
Bad Warchild.... dirty callipers, Bad, BAD!!
Break the callipers halves apart by removing the three callipers body bolts (12mm
socket) on the non-piston side of the assembly. Note Honda's use of red
loctite on the trailing threads of the bolts. You'll be working the ratchet
handle to the bitter end:
Pull the pistons out far enough to expose all the crusty brake spooge (yellow
arrow) so you can thoroughly clean them. You could go whole hog and replace
all seals at this point if you felt so inclined. Me, I elected just to clean
the dog-fuck out of the assembly, and keep going.
Using a non-petroleum based cleaner, scrub all the crusty road spooge off
the pistons and calliper body:
Now flush your shiny-clean piston with clean hydraulic fluid and re-insert it
into its respective cylinder:
Now clean out all the old dried, caked-up lube remaining inside the slider pin
boots (obviously, replace these boots if they are damaged/torn):
And thoroughly lube up the interior of the slider boots with an appropriate
grease of your choice:
( Ed note: only use proper rubber grease meant for this job. Other types of
grease may cause the rubber to bind on the slider pins causing binding and rapid wear of pads )
Apply a thin layer of this same lube on your slider pins....
And finally, reassemble these bad boyz:
Although the Service Manual calls for new calliper assembly bolts, frankly,
you're safe to use the old ones if they are in good shape, cleaned of old
thread-locker, etc. Here I'm applying Loctite Blue to the trailing threads of
the calliper assembly bolts prior to reassembly:
Torque these bolts down to 24ft-lbs (32N-m).... now, don't be messing this
one away!!!
DONE! All cleaned, lube'd, reassembled and ready for some brake pads and
Spiegler lines!
