How to Bleed Front Brakes on 73 Yam Vent

[Guest Garry J]

I would appreciate the steps to bleeding the front brakes on my 1973 Yamaha Venture XVZ12

 

Thanks Garry

First off, why do you need to bleed them?

 

I'm anal about bleeding brakes so here's MY procedure.

 

Buy a one-man brake bleeder. It is basically a tube with a one-way valve at the end.

 

Remove the caliper.

 

Remove the rear pad.

 

Put the bleeder on.

 

Crack open the bleed screw/bolt/thing.

 

With the hose pointing down in a suitable container, use the C-clamp to push the piston(s) back into the caliper. (This gets out the real old cruddy fluid)

 

Open the Master Cylinder reservoir.

 

Gently pull handle back 7/8th of the way to expel fluid.

 

Stop when either A. the fluid in the MC is too low that you need to refill it or B. when there are no more bubbles coming out of the tube.

 

Remove clamp & reinstall rear brake pad & put caliper(s) back on.

 

Pump brakes to push pistons out and to get the pads back into position.

 

Refill MC if needed.

 

 

 

 

Now that's just me. Other do it differently. One thing I should add. For dual, always bleed the one with the longest line. If the same (like on my RSV) bleed the right side only because you can watch it easier.

NO SUCH THING AS A 73 VENTURE...........NOT UNLESS I AM MISSING SOMETHING.

If you're talking about the rear and left front brake, you may need one addition. If you bleed them as directed and the brake pedal is still spongy, you probably have air trapped in the line from the rear master cylinder to the left front brake. To expell the trapped air in this line, just behind the triple tree, above the frame you can see a brake line junction. You have to remove the plastic tank cover, and the battery and the battery box. I can't remeber if you have to remove the air cleaner box or not. I hear that the later first gen. bikes have a bleeder there, but your 83 won't have one. Have somebody pump the rear brake pedal up, and then hold it down. While they're holding it down, loosen the connection. Then re-tighten it and then have your help release the brake pedal. Repeat a couple of times and the pedal will be much firmer. Push a rag in the area to catch released brake fluid, and be careful not to run your rear master cylinder dry.

Im sure he meant an 83.

There's been air in my rear/front linked system for some time now. Mine is an 83 and doesn't have a bleeder in the neck area as newer bikes have. I bled the rear brake normally last week but the pedal had to really travel for it to work as there is still air in the front brake. I couldn't bleed the front as I can't push the rear brake peddle and bleed the front wheel at the same time. I ordered some Speed Bleeders and installed one on the front wheel Friday and tried bleeding according to instructions and I could get very little air out. The directions said to pump the pedal very slowly but that left air in the neck area of the bike I suppose. Anyhow, I pumped the pedal very quickly about 10 or 12 times and then closed the Speed Bleeder and then just one more pump and I now have a full pedal and the bike stops scary quick. Those Speed Bleeders do make bleeding the system a piece of cake.
