1980E Brake caliper: grease pin dust cover

[J_C]

Is this thing supposed to connect onto the caliper hangar or is it supposed to connect onto the nut that the pin screws into. Any ideas? I had mine on the nut, but when I got new hangers off ebay the covers were installed on there instead...

Hey Jeff,

Got photo?

Hi Ed! here's the fiche:

the part I'm referring to is #9, and whether it is supposed to go on #8 or #6

BTW... got new pins. Now slides in and out beautifully! Not sure how that could be the case, but it seems to have made a difference. I'm going to repaint the caliper bodies and then test them out on the bike

Hallelujah Jeff! Finally going to get those damn brakes fixed right.

Those pins were worn no doubt, plating was gone on one side. Replacing them is the right thing to do but I agree, they didn't seem all that bad when judged individually. Guess that's the lesson here; small things add up to big things - caliper holders were definitely worn, but the pins contributed to the problem as well. Nothing left to replace anymore; you've got the stainless brake lines and Ferodo pads so you should be good to go very soon.

Please give me an update when you finally get it all back together.

Mine was on 8 when I last worked on my caliper.

The boot fits into both parts. There's a groove on both sides of the boot to fit into both parts. I put the boot onto part 8 first and then into the holder. One thing I just remembered though is that the boots that came with my K&L rebuild kit were wrong so I reused the originals... I have the same caliper setup on my 83 1100e.

I have to ask though, what was the condition of your sliders? I've been having a really annoying time with squeaking on my front end after a brake rebuild and I wonder if my sliders are worn excessively. They are worn down to bare metal in a couple of places but they feel smooth and don't look out-of-round to my naked eye. I would assume the grease would cover this but maybe not?

How much grease goes into those rubber sleeves anyway?? As in, how much is too much?

I think i may have overdone it when i rebuilt mine...

BTW, I used an OEM caliper rebuils kit that came with new sleeves; I seem to remember that the ends of the sleeve were a little different so as to accomodate the mating parts.

I think

Will do, thanks Ed! Yes, there is still no discernible difference that I can see between the brand new ones and the old ones, besides the "wear" but it seems to have solved this problem. Will know much more once I get the fluid in them! I'm hoping to get them painted this weekend and to get fluid in there sometime next week. My bike has become jealous of my law books, I'm afraid.

Josh, thanks! This makes MUCH more sense. I'll give this a look next time I'm outside.

In terms of the pins, yes, mine looked the exact same. However, inside the caliper hanger we could also see wear (once we cleaned out the grease). The problem I was having (we suspect) was that, somehow, the hanger and the pins were getting slightly cockeyed and hung up on each other. I'm hoping that once these go back on they'll be good to go!

Put the books down and send me some nice shiny brake lines. The good karma will fix your brakes.
