1994 GL1500 Interstate/ No Rear Brakes Help needed

Post by randog »



I need major help. 1st time here.
Bought the Wing 2 weeks ago. I was informed it needed the rear Master Cylinder rebuilt and was given the rebuild kit with the sale of the bike.
I never Have done this before and had I have known what was involved I would have walked away. I trailered it home and drove it 6 miles. The front brake works great. Absolutely no rear brake. No leaks.
*** I purchased a bleeder kit and it seems to work well.
*** I've rebuilt the rear master cylinder. Previous owner had replaced the front and rear discs along with both tires.
*** I bled the front brake because the manual reads to do it first. No air came out at all and the front well is full.
*** I've pumped the foot brake hundreds of times. I put a weight on it and have bled the rear using the bleeder kit
and not used the bleeder kit. Air comes out along with brake fluid. I've used one full bottle so far. I'm using Pro Honda
DOT 4 fluid. Need another bottle as I emptied the new 12 oz bottle I bought when I began this project.
*** The foot brake hasn't got stiffer at all. The zirk and lines don't appear to be leaking at all.
I need advice!!!
I measured the cylinder pushrod length and it's just under 4 inches// what Manuel reads.
Full of arthritis, I can manage working 3-4 hours a day. Today is my 3rd week. Need to get riding b4 summer ends.
Ideas WANTED and NEEDED!

The left front caliper is also controlled by the rear master cylinder. You need to bleed the left front caliper after you bleed the rear caliper.
The right front caliper is independent of the rear. It is controlled by the hand operated lever on the right side handle bar control.

Thanks Mike. Before my manual arrived, I tried to bleed the rear. Manual showed to blead front left. I did, no bubbles at all. I bled the rear and had a lot of bubbles. I ran out of Pro Honda Dot 4. Honda / Yamaha shop closed Monday and buying more this morning. Do you know if Pro Honda dot4 is synthetic? I almost bought a quart of another brand from auto zone ( much cheaper) but decided to not mix brands. The Honda bottle doesn't read if it's synthetic.
*** I've used up the entire 12 oz of new brake fluid. I've pumped the foot brake a thousand times. I bought a bleed kit tool and it seems to work.
The foot pedal has no pressure at all.
Previouse owner bought and installed new discs front and rear. He also gave me the rear master cylinder rebuild kit. I used it.
I've bled plenty of car and truck brakes back in the 60's-80's. I'm stumped.
Thanks for your time.

I have to admit, I have never used Honda Brake Fluid. I normally use Prestone Dot 4 which is synthetic. But, I also use Super Tech Dot 4 from Wal Mart. I don't know if it is synthetic or not but I have not had an issue with it or any other brake fluid. I change it every year.

Did you bench bleed the rear master cylinder before you reinstalled it to insure that it was working after the rebuild?

Hey now! I didn't know to bench bleed. I called Honda tech dept and said Dot 4, any brand ok.
I've got a Rear brake! I re-bled the front and then the rear.
Now I have one more glitch I was told about by the previous owner. He told me a plastic at the top radiator area was cracked.
I want to remove the radiators in order to locate the leak and replace all of the hoses. After that, new timing belts.
Thanks for sharing your knowledge. I hope o enjoy a couple months of riding this season.
Having owned a 1998 Valkyrie for 15 years, dealing with all of the GL's plastics, I'm inclined to bob this ol girl over winter.

Glad that you got the rear brakes solved. I wouldn’t put the timing belts off too long. It could spell permanent damage to the motor(valves,pistons) if one tears, especially if you don’t know when they were last replaced. But I’m sure you’ve already been told that.

Long ago I had a 1982?? wing I let a guy ride and sure enough the belt broke and fried the engine.

HOW IN THE WORLD do I get the front fairing off of my 94 interstate. There's a leak of antifreeze the seller told me
was coming from a plastic part.
My GL1500 SERVICE MANUAL & electrical troubleshooting isn't showing me where all of the screws/bolts are to take off.
I've been all over youtube and I haven't found any 94 vids.
All of the plastic BS I'm not a fan of. I've owned 3 new bikes in my 61 years of riding.
Honda 600-700 ??, Harley- 80-80, and the best scoot was a 1998 Valkyrie. I like the fact not a lot of gingerbread to get to what
you need to get to without the tupperware.
Bobber maybe in the future for a winter project.

Start with the how-to for doing the timing belts. You'll get a lot of the Tupperware off. If necessary, go on to the one on changing air filters (which you probably ought to do anyhow).

Thanks. Air filter is new per my inspection.
There's got to be a diagram somewhere to remove or show the bolts that need to come out in order to remove the fairing. I found something on this site. I touched the wrong button and can't find it again.

I can't tell you where all of the screws are, but I removed and replaced mine while still on crutches after hitting a pile of grass, on a curve, at night, just after meeting an oncoming car. Don't just start yanking on it. gentle tugs and some looking will help you figure out where they are. Get the side pockets out and you can see inside, get all of the Tupperware out of the way, it all has to come off too. A box of sandwich bags will help you remember where all the screws go when reassembling (mark the bags). It really isn't that hard. Just take your time. An old 5 gallon bucket makes a good seat and puts you at the right height for a lot of the project. Look at how to remove the radio, and that will help you along the way, as well as the windshield. There are probably videos of them.
