’79 GS850G caliper rebuilt kits

[sarathchandars]

I tore apart the front and rear calipers to assess the state of the system. Having found that all the rubber parts have to be changed, I scoured the internet to find parts. For a '79 GS850G (as opposed to '80 or newer), partszilla doesn't have the important bits. on eBay I found a rebuild kit from K&L for the rear caliper but nothing for the front that has the 4 dust boots. Any chance anyone can recommend where I can get it? From partszilla I found the part numbers in the picture.

In the worst case, is it possible to have front calipers from the '80 or newer GS onto a '79 fork?

Out of curiosity, what are the shims for in the rear caliper?

And be sure to clean out the masters, and replace the brake lines.

You are the best Nessism. For sure brake lines are next in line. Any suggestions for where I can source them for reasonable price?

Lastly I saw some minor pitting at the bottom of the piston but nothing on the sides - is that something to worry about that would warrant a replacement? I was guessing not but would love your thought.

Check the thread on how to make your own brake lines using made in USA Earl's parts. That's what I use. And they are one of the cheapest methods also.

Take a look at Apex Brakes for the lines. I just ordered a 4-line set for my 1979 GS1000 that were $138 total shipped to my door.

Is this the website you used to order those? http://apexbrakes.com/custom.asp Or would you recommend I email Raymond?

[1978GS750E]

I always just email Raymond. Normally get a response the next day with pricing and an offer to send a paypal invoice.

I've purchased probably 6-7 sets from him without any issues.

If you use the newer calipers 80+ you need to use the newer rotors with them from memory.... If you're not bothered about originality that bike also works with the Twinpot caliper and CBR rotors upgrade.
