Front Brakes seem to Sensitive

Postby JManton » Wed Nov 10, 2010 4:11 pm



Hi Everyone;
I bought a 2002 GL1800A a short while back. The problem is the front brakes are in my estimation to sensitive. When coming to a stop from normal hwy speed they act OK, but at slow speed (less then 10mph) it seems like the slightest increase in pressure causes the bike to almost nosedive. The pads seem almost new and were probably put on by the previous owner. I don't know what type they are or even if their the problem. The rear brake seems OK, but I prefer stopping most of the time with the front. Any Ideas?
Jim

first and easiest thing is to check to make sure you don't have too much brake fluid in the master cylinder...you could also pull the pads and push the pistons back into the caliper...while you have the pads off you can look them over and see if they are oem or some aftermarket flavor...maybe they are the wrong pads for the application...

I am with gereva1 on that but also there could be dirt in the pistons keeping the pistons out and the brakes 'on'. If you take the pads out as suggested just clean around the pistons using an old tooth brush etc.

It might be useful to try another GL1800 to see if what you perceive as too sensitive is in fact normal for that bike.

In addition to the things mentioned above, make sure the pads are not contaminated with brake fluid and the calipers are free to move in and out on the guide pins. ;)

Something else I didn't think about was your comment about the bike nosediving...this shouldn't happen unless there is a problem with the anti-dive valving system, or if the previous owner disabled it...any chance the previous owner swapped the fork springs? Disabling the ADV is a common task after upgrading the front suspension...I disabled mine after putting in traxxion fork springs, but I didn't like the feel of the bike in parking lot play (the front end bobbed, which I know was my fault, but if I have a system that will level it out without my extra effort, why not use it), so I undid it.

The bike isn't locking its wheels I assume (especially since it's an abs bike), so to me a bike can't stop too fast so long as the wheels don't lock up.

Does your brake lever operate smoothly, or does it feel notchy? When you pull in the lever there's very little braking, and then the lever kind of jerks/clicks and suddenly the brakes grab?

First of all Thanks to everyone that replied. To answer one gentlemen's question, I have been a Wing owner since 1984 but this is the first bike I've owned with the interlock/proportional braking system and so I know how the brakes should react.
I've tried to follow all the great replies and I did find the reservoir filled to the top. I brought that back to reasonable.
I'm in the process of changing the front pads (new one's should arrive tomorrow) with OEM pads, and I removed the calipers to clean everything with brake cleaner. The brake handle seemed to operate smoothly and so I doubt that was the problem but it was a good idea. I don't think that the ADV was disabled but seeing I didn't know one even existed I'll check into that possibility further. I'll let everyone know how this project turns out, and Thanks again.

Al is well. I don't know if it was the fluid level adjustment, new brake pads or just cleaning that did the trick but the brakes now react as they should. It takes a little more brake lever then it did but other then that the brakes are working smoothly and without the sensitivity that exsisted before. Thanks again to all who tried to help.

Glad to hear you got it fixed, but it always bothers me a little when I don't know why it fixed (I fear the problem will come back!)!!
Enjoy riding the wing.
