Yet Another Disc Brake Question

[Chazzer]

Hey Toro Guru's,

Would any of you know if I can keep my drum brake adjustment valve as seen below?

I have fit tested my 69 disc brake booster, master and metering valve combo. All the brake lines line up perfect. They both use the same distribution block.

Here is a pix of the 68 drum brake set up

Here is the 69 disc set up. Notice how all the brake lines all line up. If i can keep the drum brake adjustment valve. I'm pretty much set.

Does anyone know what the difference is between the drum brake booster and the disc?

The only difference I have determined so far is the eyelet that hooks to the brake petal has a slightly smaller diameter on the 69 disc booster.

I am not completely certain but it seems reasonable to think that the boosters are pretty much the same. As for the rear adjustment valve I am pretty certain you will need to use the version for disk brakes as there is a difference in the proportioning between drum and disk front brakes.

I did not do a drum to disk conversion so it is not my area of expertise, my comments come from a general knowledge of how braking systems work. Specifics may vary from situation to situation, so it would be wise to mimic the disk brake setup when you convert; that means the valve probably needs to be replaced with whatever is on the disk brake setup.

Thanks for your input X.

I thought there could be a difference from drum to disk. However I cannot seem to find any markings or stampings on the valve. Which makes one wonder: how in the heck could they keep things straight during assembly!
