Bleeding brakes

Postby ihunt » Sat Jun 02, 2012 5:55 pm



I've read different forms about how to bleed the brakes on a 1989 gl1500 Goldwing. For some reason either I'm doing something wrong or I have a major problem my footbrake is still soft but I have front brakes. Do anyone have any suggestions.

Check the master cylinder for the foot brake as there may be some muck (call it what ever you will) stuck in the bottom of the cylinder. Clean it out and pump a small bit of brake fluid thru to see if it is all clear then do the bleeding as per normal.

I am fairly sure youi have linked brakes the right front is part of the rear system..bleed it first then the back brakes. The front lever only works the right front caliper..at least that's how it is on other GL's linked systems.

I think it should be the left front and the rear together. That is how it is on my 1500.
If you have bled the brakes and still have a soft rear pedal then there is air in the system. Some times it is hard to get the air to move out. One trick is to place something heavy on the rear brake pedal to hold it in the down position and leave it over night. I used a gallon paint bucket with paint in it on mine. Hung the bucket handle on the brake pedal for 24 hours. This should let the air move into the master cylinder and then you will need to add more brake fluid to the master cylinder.

Check that the one of the brake pad pistons have not jammed as that will make the brake soft.

Yep, left front is the linked one..thinking backwards my mistake. Also the problem with the hold the brake pedal down is that the master is not the high point in the system..works for front brakes as the master is the high point.

I just went through that.

I rebuilt my rear master cylinder and both left-side calipers (which are controlled by the rear master cylinder)

It took many many pumps of the pedal to get all the air out.

-Pump the pedal with everything closed many times.
-Start with front brake and bleed, bleed, bleed. I had the best results using the two-man up-down method. One working the pedal and the other working the bleeder valve. It will take a while.
-Go to the rear brake and do the same thing.
-You may need to close everything and pump the pedal again to flush the air to the calipers.
-The master cylinder pushes a small amount of fluid with each press so it will take a while.
-It took almost an hour of back and forth to get all the air out.

Be patient!

I know this is an older thread but is is good information and answered the question I had. Thanks.

I use a Pneumatic Brake Fluid Bleeder from Harbor Freight on my Goldwing and on my cars. It works great and will get all the air out. Since I replace the brake fluid every two years this is a must have for me. Just thought I would share with everyone. Here is their link and they will ship if you don't have a Harbor Freight near you.
