78 750 single front disk

[MR.G]

Hey all, have not posted in a while. Question...1978 GS750 single disk up front. Has anyone replaced the basic 3 part brake line with one single line. Ie the upper line is about 18", the lower portion is about 22" and the fitting that joins the two is about 2" (the part that mounts up under the fork brace under the head light). So a continuous brake line, I would think, would be better? Has anyone done this? If so what brand did you use? One other question, the handle bars are not stock they are allot lower, not flat but about a 3" rise, how much shorter of a brake line should you use? I don't have the original bars or I would measure the difference. Don't want to use the original line as it is way to long with these bars. Thanks to all

You can have them made any length you want. It will be up to you to measure, then tell them what type of banjo ends you want on them.
There are lots of different companies, BassCliff might have a list on his website list of vendors. I have even heard of some going to an eBay vendor, but the name escapes me.
But yes, there is nothing wrong with going with one long line if it floats your boat.

You can use a one piece but be careful about mounting it

The up and down motion of the fork can make it saw into your triple clamp

[koolaid_kid]

You need to have standoffs with rubber washers in the center to keep it in place.

I am just wondering why there is only one dics up front? Should have 2 on the 78 750. Is this a wire wheel or mag you have? If its a wire wheel then you have a 77 rim. That would explain why only the one dics. If you take the rim off youll see that the right side is drilled and ready for the second rotor. Youll have to get a double disc splitter, another caliper, and the hose to do the mod. And contray to popular folk lore, the master cylinder for the single will be ample for the double as well.

Click on myn avatar and go to the bottom and look at my albums for the pics of my 77 and the 78 differences.

I don't know. My 78 GS750 with wire wheels only have a single disc in the front. I don't think all 78s got duals.

[tkent02]

No, my '79 didn't come with dual brakes either.

[chuck hahn]

Yeah wasnt think that it might not be an E model. But did your 78 single discer have wire rims or mags? Thats probably the difference. in any case he can add the second rotor as i described. Makes for better front braking having 2 available.

[chuck hahn]

I will have to take a look at the 77 next time i am over there..but i am 99% sure it is drilled for another rotor. In any case, any rim thats already drilled and the right size can be swapped in for the addition.

[Road Rash]

Still, you need the proper fork bottom. If your bike's a single disc front, it's not gonna have the caliper mounting boss on the right fork bottom.

[tkent02]

Should be drilled for the second rotor. The 550 I'm doing had set screws threaded into the holes. You will need both fork legs, as the brake mounting points on the single disc fork is located for the bigger brake.

[chuck hahn]

Yeah that too..those are as plentiful as candy at the store. Caliper bodies are common place too and cover many models and years.

[chuck hahn]

If I am remebering right Tom, theres a big black steel cover plate over the right side on my 77.

[tkent02]

Probably plastic? Under that will be the threaded in screws. Remove those and the disc bolts right on.

[chuck hahn]

Yes Tom, that rings a bell. Has the three knobs that snap it into the rotor holes that are predrilled on the right side. Protector shield i guess you would call it.
