Topic: Johnie's 76 GL1000 Sulfur Yellow Build

[Johnie]

Sil-Glyde for the pins.

Geez, glade I asked. Do I need the Dow anywhere? Like between the piston and back of brake pad to reduce squeal?

I remember a fellow on here a few years back using that special Dow grease on the piston rubber seal..

[Johnie]

I use Raybestos brake assembly lube on the piston seals. I was pleasantly surprised at how smooth the pistons came out. No rust either.

[RAFster122s]

You can use the Dow everywhere except the seal for piston… it gets Castrol(etc) red rubber grease or brake fluid for installation.
The Dow will not move from where it is placed unless mechanical action moves it, it is temperature stable beyond 600F whereas the Sil-Glyde is gonna start creeping before you see those kind of temps if you are really wailing on your brakes repeatedly in curvy mountain roads… brakes typically aren’t going to be operating in that temp range. You would be boiling DOT3 fluid and probably DOT4 at 500F, forget DOT4’s temp range.

Thanks all...I sure appreciate your help with this build.

Just poking my head in the door to see if there is 'fire in the hole ' yet. 

[Johnie]

Hey Eric…I don’t expect fire in the hole for a while with summer and family. Thanks for checking in and have a great 4th!

[Johnie]

I spoke too soon. One of the rear caliper pistons has a small rust pit. I measured and it’s located at the top of the piston and may not come in contact with the seal. Thoughts???

Did you put the piston in the bore w/o the seal to see where the pit lands compared to the groove?

[Johnie]

With the seal out I can't see where the pit lands as the piston bottoms out. I suspect the piston doesn't bottom out under normal use. If that's the case the pit would be above the seal.

It will when you go to put new pads on for clearance to the rotor. If it's below the seal it can cut the seal.

[Johnie]

Pads are really good with 15,000k. However, I will error on the safe side and get a new piston. Thanks Stu!

[Johnie]

Got the front calipers off and l am now in the hunt for 2 more pistons. I just would not feel right or safe putting questionable pistons back in. They both had rust pits right on the seal area.

Johnie,just for curiosity:what diameter are those caliper pistons ?

Did you try Randakk's site? They specialized in gl1000 parts.

Hey Johnie, you might consider upgrading to the superior two-piston calipers as mentioned here:

It can be done using factory parts on your wing; Don R has done it on his and can help with any details. BTW, out of the 10 or so of these calipers I've seen, none had any pitting on the sides of the pistons, and needed no more than cleaning to put back into service. If rubber parts or pads are needed, they are readily available, as Honda used them on a wide range of models. I personally wouldn't waste any time or money on those 38mm Leadwing slugs, unless you prefer the stock look over good braking.

These dual piston calipers(30 or 32mm pistons  )look like the best upgrade,if they will fit his GL1000 forks.

[Johnie]

The pistons are 38mm. I have them coming from Godfrey Garage in Milwaukee area. They will all be the phenolic pistons. I have used them on some of the 750's too. I want to keep the same OE look here. Thanks for the ideas all.

[Stev-o]

I even used it on the inner fenders in the motor compartment of the Chevelle.

Hi Johnie...how is that Chevelle?   You're about to be in the middle of your car season, lucky you.  I'm in boating season, too hot for the Corvette.
Hey Stev-o...yes we are in the middle of the car season. I'm going to be rebuilding the carb soon as I had an issue with the float sticking...of course when I was heading to a show. It's time...according to the PO it has been on there for about 15 years with limited miles and no issue. So I think it's time.

Sorry to hear that it needs a rebuild in the middle of the season.  Holley or Quadrajet? 

[Johnie]

The Chevelle has a Edlebrock Stev-o. One of my muscle car friends specializes in these so I'm in good hands...LOL

Hi Johnie,was wondering whether the carb. on your Chevelle you'll be rebuilding is a Holley carb. or a Quadrajet carb. ??

That surprises me, would have lost that bet!

I used one of their master cylinders and I works very well.

[Johnie]

I decided to give those shocks a try and will report back here. I am not an aggressive rider and think the Hagons are really more than I need.

[BenelliSEI]

I’ll bet they’ll be fine. They look good too!
