Seized front caliper retaining pin !

Postby doubledown » Thu Feb 07, 2013 2:56 pm



I'm attempting to do a brake job on my new-to-me 1982 GL1100. I started to dismantle the calipers (following the guide on the site) and one of the retaining pins is impossible to budge! The other 3 took a little coaxing, but eventually slid out. The final one moved about a quarter of an inch, and will not budge. I've tried WD40 and another penetrating oil. I've tried heating the caliper a bit. I've tried a hammer and a pin punch. I've tried gripping the other end with pliers and pulling. I was thinking about rigging up some sort of C-clamp to be able to twist some force into the pin, but I don't see that working if a hammer wouldn't.

So what am I doing wrong here? Is there a very simple method that I can't find? Any help is appreciated.

As an update, i just beat it until it finally moved. :) Also found out that, for some reason, the pins are not listed as a part under the 1982 gl1100I....but ARE listed (and still available) on the parts list for the 1982 gl1100 standard.

Yup, you did exactly what most of us do - just bash on it until it comes out.

Now, before you put it back in, take some sandpaper to it and take the coating of oxidation off the surface, so you won't have to go medieval on it next time to get it out. :)

Also if you didn't, you need to push on the pad towards the pin as there is the spring behind the pad that puts pressure on the pad to keep it from rattling around. Same with installation of the pads that way the hole is centered on the pin. Only need to sand the pin smooth ands then lube the pins with copper brake caliper lube.

Here's a followup question (I can either make a new post, or keep riding this one): I have the breaks completely disassembled, and the pistons are a little gummed up. I've been sanding on them a bit....and there's a some spots that are pretty bad. Maybe not completely gouged, but a much darker color than the chrome. Should i keep sanding, or does that mean i need new pistons?

If they are pitted, replacement time.

The major problem with worn or pitted pistons is drag within the caliper bore and failure of the piston to move away from the pad when the lever/pedal is released. This extra drag consumes power, causes premature wear of pads and rotors and reduces braking effectiveness.

A photo of it would help with analyzing it. If they are pitted, yes replace them. But in your post, you say darker. I'm not sure what that means. I have an extra right side, front caliper around here, but am not sure what shape it is in inside. P.M. me if you need it.
