Proportion valve rear brake? I lost the spring

[Arxvz1200]

So it is one those days. I  decided to clean the rear brake cylinder and proportioning valve.

Like the title says the damn spring flew across the air....and I never found it. 

I guess this marvelous thingy proportions pressure to rear and front?

If the spring is removed what will happened?

Thanks

Yep, you will needs it, keep looking or delink the brakes, which means that both front rotors work off of the handle bar and only the rear is activated by the foot pedal.

I Just got rid of the proportioning valve and delinked the brakes. Had too many situations were the front brake locked up on slippery or gravel surfaces causing the front wheel to slide out side ways on me even at the lightest touch of using the rear brake pedal only.

I got rid of the proportioning valve, delinked by blocking the brake line to the front. Pedal now operates the rear only. 

Not ideal. but at least now I have brakes. 

Can I operate the 2  front calibers with the original front master cylinder?

Yes you can use both front calipers. @skydoc_17sells a complete delink kit to solve all the problems. He’s gone on vacation right now, he has a new grandson, but can fix you up.

You can. You will however notice a slightly softer and longer stroke feel on the lever at the same time quicker front brake response. It may take you a few stops to get use to the different feel.

Hey Ronnie,

Thanks for the Props!

Anssi I do indeed offer a De-Link Kit for the First Gens. That connects both of the front brake calipers to the right side Master Cylinder and connects the rear brake caliper to the rear master cylinder and foot pedal separately. I will be home from my California trip Saturday of this week. If you are interested, please feel free to PM me Anssi.

Here is a link to the De-Link Kit found in the Member Vendor's Section of the FOrum:
