Poll: How many are having problems with rear Brakes?

[thumper_imp]

Does your non-ABS model have the proportional valve on the left front rotor? I'd always thought both models had Linked Braking System (LBS).

[the Ferret]

Nope no proportional valve and only ABS is linked which was the main reason I bought my non ABS

[the Ferret]

Would someone with an ABS/ linked unit please verify this?

The linked system is only on the abs models. It is easy to test. Put bike on centerstand. Make sure sidestand is up. Start bike. Put it in gear and let out clutch. rear wheel will spin. Pull in clutch and grab front brake lever. If it is linked it will stop or slow the rear wheel.

Now....

Turn off bike and have someone put weight on back, getting front wheel off ground. Now manually spin the front. Now depress the rear brake pedal. If you have linked brakes the front wheel will slow or stop.

The linked system/combined braking is one reason why I too shy'd away from an ABS model (which was my original intent).

You're almost correct. There is a proportioning valve (very easy to see on the ST's left front caliper. Merely pulling the brake lever, while the front tire is spinning in the air, will not activate the valve. The brake disc has to have enough force against it (like a tire slowing on pavement) to have the valve depress, which will then activate the rear brakes of the bike. You could also accomplish this by getting the front tire in the air, pulling the brake lever hard enough to stop the tire, then manually apply enough force against the tire/wheel (forcing it to turn) to see the proportioning valve push into the assembly. Then, your back tire will stop spinning.

These show the differences between the std and the ABS models for the brake routing.

Thumper yes there is a proportionong valve on my ST, no such valve on my CB. To test proprtioning valve/ linked brake on thie ST I put it on centerstand lay next to bike on left side, spin rear wheel with my foot and manually push proportioning valve foward the front. After proprtioning valve/ linked brake stops wheel, I let go and wheel will spin again.

Ferret, I have ABS and I did the test you requested. The rear brake stops the front and rear wheels. The front brake only stops the front wheel. I believe this is the way linked brakes are supposed to work.

+1, that's how the Combined ABS works on the CB1100.

Ahhh very good, Thanks Terry. So on the linked/ABS model equipped bikes, ..the front lever activates the front brake only. The rear pedal activates the rear brake AND some of the front brakes.

On the NON ABS the front lever activates the front brake only and the rear pedal activates the rear brake only.

Thanks, clears it up definitively for me.
