Many people say the 1500 and 1800 Goldwings have linked brakes. It's my understanding that they actually have integrated brakes. The terms aren't interchangeable, but some might think they are.
In a linked brake system, when you press the brake pedal, a portion of your braking pressure is transferred to the front brakes as well as the rear. Also, when you apply the front brake lever, a portion of the braking effort is transferred to the rear brakes.
In an integrated system, the brake pedal operates the rear brake and the left front brake, while the lever operates the right front brake only.
Am I wrong in how the brake systems of the 1500 and 1800 models operate?

That's how I understand it as well. Of course that's from reading my Clymer manual so there could be room for error.

Hi everyone. I can think of one other thing to add. Applying the front brake lever applies braking to the left front caliper. During this braking action, the caliper rotates enough to apply pressure to a cylinder, which in turns, applies hydraulic pressure to one of the rear brake caliper pistons. To me, this would mean integrated.

I've not been around the GL1500/1800's much but I thought the brake calipar on the front was a triple piston setup, with two pistons working from the hand MC and the piston in the center was worked by the foot MC. I would guess that the way the calipar was built is the outer pistons are linked, so fluid will flow through them. The piston in the center is a seperate chamber. Another (possibly better) way to look at it is that the triple piston calipar is just two seperate brakes in one body.

Mind you, I know everything about nothing and nothing about everything.

Explain it anyway you wish, I still dont like the system while riding in sand/gravel, or over wet grass...

The front brake lever on the 1500/1800 operates the right front caliper only. They are only a 2 piston design. The brake pedal operates only the rear caliper and left front caliper. All calipers are a 2 piston design. This is a Linked brake design on these bikes, that got it start on the 83 Goldwing. The only difference from 83 to present is the addition of ABS to the ABS model of the 1800. I hope this clears up the confusion.

So Gene, your description of how the brakes work is exactly as I'd understood it, but I thought it was an integrated system. From what I understood, a linked system operated the rear brakes from the lever on the handlebar as well.
If I'm wrong, what is an integrated system?

A intergrated system is one that either the front brake will operate the front and rear brakes or the pedal will operate both front and rear. Linked brakes mean that one master cylinder will operate 2 brakes and one mastercylinder will operate one brake. They are very similar, but the handgrip mastercylinder on the wings only operate the right front caliper, with the pedal mastercylinder linked to the rear and left front caliper (thus the term linked). Intergrated brakes can be fuzzy in the defination, the early wings both front calipers were intergrated to the same mastercylinder, but some bikes have braking systems where the front mastercylinder works both front brakes and the rear brake, and it's rear mastercylinder works all three brakes also. Murgie's photos are not of the 1500 braking system, I know that from actually doing the entire braking system. Now it is possible that the picture he has posted are of the 1800 ABS braking system, I haven't had to work on one of them. Hope this helps.
