linked brake bleed question

Post by made2care » Mon Mar 13, 2017 8:03 am



I have a 1980 gl1100 whereby the front left and rear brake is linked. I am wanting to change the brake fluid, is there a sequence (front left first then rear, rear first then front) or are they done at the same time?

always do the farthest brake first, start with the rear then move to the front.
at least that's the way I was taught to do it

OK................

the 1980 came from the factory with separate front and rear braking systems. 1983 was the first year for the linked system. so if you do have linked brakes on a 1980 then it has been modified from stock.

that said............ the front brake is the farthest from the master cylinder as the proportioning valve is near the swing arm pivot.

So you are saying that if not modified from stock, the front brake lever controls both left and right front calipers?

You are correct. i assumed it was the same as a 1200 i had previously owned ( should never have sold that bike). Okay, time to rebuild brakes.

I am working on an 83 Aspencade, front left caliper is front brake and right caliper is hooked to the rear brake. I can bleed the rear caliper using the pedal , but i can;t get any life to the front line. Is there a common area that plugs up?? I used a mighty vac on the front right caliper but it will not draw any fluid.

OEM service manual has the front brake of the linked brakes done first then the rear. May have to do several times in that order. The highest point in the linked brake system is the line going to the front brake - goes up and over the engine and down by the front forks, lots of line for air to get trapped.
