I am the original owner of my '80 CX-500 custom. I am re-building my master brake cylinder which has a piston that measures 50mm x 13mm.

I ordered the current rebuild kit from honda.

The kit contains a piston that measures 55mm x 15mm: this is for a '80 cx-500 custom.

So I checked with a couple shops to verify their kits....55mm x 15mm

OKAY FINE, I HAVE A WEIRD MASTER CYLINDER, SOMEONE AT THE FACTORY SCREWED UP 26 YEARS AGO AND BUILT MY BIKE WRONG.

So I resign to go on EBAY to find a replacement MC and just rebuild it and I just bought a USED master brake cylinder assembly-which is a P.O.S., all rusted, and gunked up, etc.....and guess WHAT? it is the exact same piston size as what I have.

Has anyone out there rebuild a 1980 CX500 custom's Master brake Cylinder and run into this screwed up situation?

I am posting this on multiple boards because I am LIVID and outof my mind with frustration.]]> vdotmatrix Braking System Fri, 07 Jul 2006 18:27:49 -0700 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7257,7257#msg-7257 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7257,7257#msg-7257
While I had the rear wheel off last week for a new tire to be put on, I decided to go ahead and replace the brake shoes. The old ones looked to be in pretty good condition, but with everything that had to be removed from the bike in order to get the wheel itself off I figured I'd save myself the hassle later and replace them at the same time. Anyway, there was a small amount of squeal from the old shoes the 1st couple of times brakes were applied after sitting overnight, but with the new shoes the squeal is even worse. The drum is in great shape, bike only has 11,000 miles, but i'm wondering if I missed something. I made certain everything was clean before reassembly, and I'm not looking forward to dis-assembling the rear end again to remove the wheel, but something needs to be done.

What are some possible causes, and their remedies?

TIA for all replies!]]> drknobs Braking System Thu, 06 Jul 2006 09:30:10 -0700 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7241,7241#msg-7241 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7241,7241#msg-7241
This is a big bummer because Honda probably won't take these back and I paid $45usd.

The bike is a 1980 cx-500 custom; I am the original owner. THIS IS THE PART KIT LISTED for my bike at gobinet that I ordered from Honda.

Does anyone have any ideas?

The housing has some numbers embossed on the bottom of the housing.]]> vdotmatrix Braking System Fri, 23 Jun 2006 04:26:41 -0700 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7236,7236#msg-7236 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7236,7236#msg-7236
My cylinder re-build kit came with an extra washer. There is a rubber cup which isn't the one that is on the piston itself that I cannot determine whether it faces in or out....

Little details like this could spell big time frustration at re-assembly time.

Are the any detailed diagrams anywhere for a 1980 CX500 custom (square cup)]]> vdotmatrix Braking System Wed, 21 Jun 2006 23:42:05 -0700 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7196,7196#msg-7196 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7196,7196#msg-7196 Anybody know if I need the mounts too?

I just bought the rebuilding kit, cleaned all the gunk out of the master cyclinder, have replacement parts for everything above the o-ring....now I want to reassemble this thing and go riding.....

I can't find any documentation on rebuilding the rectangular 1980 model brake.

Can anyone help?]]> vdotmatrix Braking System Wed, 07 Jun 2006 12:51:59 -0700 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7177,7177#msg-7177 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7177,7177#msg-7177 I had changed the brake fluid previously to replacing the hose and ran it for a couple weeks as a baseline measurement. When I changed the hose out, I emptied and replaced the fluid again using fresh fluid from the same bottle. bled it and tested the upgrade.
This is an easy upgrade that IMHO imporves the performance of the front braking system. My next step will be to upgrade toa CB900 caliper to improve stoping power.

In order to have a baseline and as part of my process before making changes I:

Made sure front rotor was wihtin service limits using a micrometer
Pulled and inspected brake pads,
Roughed pads up with fresh 80 grit sand paper
Cleaned pads with air and brake cleaner.
lubed mounint holes and clips.
re-assembled and installed then cleaned everything again with brake cleaner.
Changed fluid and bled system
cleaned entire assembly with brake cleaner again.
Rode for 2 weeks

Replaced line, added speed bleeder, bled system cleaned with brake cleaner.

I used universal DOT approved hoses that use compression fittings. that I found on ebay. There is a shop in NV (i think)that has hoses up in various lenghts most all the time. Measure your existing line from the top of the swaged or crimped on fittings for an overall length. If you have a dual front brake system measure all 3 hoses the same way. If your a little long (1/2 to 1") when you finish assembling the hoses dont worry, it wont affect braking. To find the correct fittings, I compared the size shape and angle of each fitting (120 degree angle 10 mm banjos in my case) and searched for comparable items. I used chrome plated brass fittings instead of stainless because of price. Either material will hold up under the pressure on the brake lines. With this project you MUST replace the crush washers! These are the brass washers that are between the bolts and fittings. Usually 2 per bolt 1 each side of the fitting.

Dual front brakes hae a T or Y splitter so you can either use compression fittings to attach each hose or use Banjos and Banjo bolts depending on the splitter Or you can use the OEM one. If you reuse the original and it's rubber that will be your weak link in the system.

Pitfalls, None really, Just dont over tighten the compression fittings or the banjo bolts.

REPLACE ALL THE BRAKE FLUID!!! Drain the resivoir and caliper. Use good brake fluid. I went thru a whole bottle of DOT 5 synthetic to make sure I had the system filled with clean fluid. and I'll change it in about a year to keep the maximum performance of the system. condensatin still gets in the system and I don't like corrosinin my calipers or master cylinder]]> KBKeller Braking System Sun, 04 Jun 2006 07:30:39 -0700 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7094,7094#msg-7094 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7094,7094#msg-7094 Will have all the parts next week and will assemble, install, test and, if anybody wants to know, report the status of the project.]]> KBKeller Braking System Sat, 22 Apr 2006 07:50:37 -0700 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7089,7089#msg-7089 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7089,7089#msg-7089 william harris Braking System Thu, 20 Apr 2006 12:41:04 -0700 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7088,7088#msg-7088 http://www.aegeansoft.com/silverwing/phorum/read.php?33,7088,7088#msg-7088 KBKeller Braking System Thu, 20 Apr 2006 20:55:10 -0700 http://www.aegeansoft.com/silverwing/phorum/read.php?33,5365,5365#msg-5365 http://www.aegeansoft.com/silverwing/phorum/read.php?33,5365,5365#msg-5365 Are there other rotors available from other makes or models that could be made to fit using the existing rotor hubs?

My front brake seems to think its an automatic parking brake system.. For some reason while parked the front brake magically applies its self to the point that the bike simply won't move till I get my handy little
wrench and crack open the brake bleeder at the caliper then away we go.
I ride the bike to work about a mile. I have to crack the bleeder to go to work and when I get ready to head for home. Every day ! We bought the bike in Utah and rode it home to Oregon. Never gave us a bit of trouble.
It sat here at home for about 3 weeks while getting title trans and insurance Ect. After all that monkey bizz I decide to take it for a quick spin to town and .....HEY it won't move.. One time since my first encounter with the problem it was free after an overnite period . However within a half mile the brake came on and stopped the bike. I cracked the bleeder and finished the ride to work. Anybody got an Idea as to how I mite cure
my parking brake problem..

Thanks...
Clancy..

That being said, I wanted to ask about the brake calipers and if they can be put on either side. I currently only have one operating and it's on the right hand side.

So should I try to file the inner part of some thick automotive copper ones I have or just run up to the hardware store and use brass or bronze washers? The last option would be using two of the thin copper washers next to each other.
