Re: Anybody running manual disc brakes? Pics

A stock 71-72 combo valve would be perfect, or you can run an aftermarket adjustable prop valve - but you are correct in that the original distribution block from a 69 is not the correct valve for your soon-to-be-modified brake system. It appears you have the correct mc in your 1st post; assuming you purchased a manual brake mc (for disk/drum), it should have the deep hole in the rear piston (as opposed to the little shallow hole that accepts the short intermediate push-rod associated with a booster. Recommend check that your mc has a deep hole piston in the bore where it accepts the brake pedal pushrod. If it doesn't, i.e. just has a shallow little depression where the push-rod goes, then you may have a power brake mc (for disk/drum).
thank you so much for that detailed explanation, no where did it say if this was for manual or boosted, I was just happy to find one for disc/drum instead of drum/drum

I will check like you suggested
