Re: Brake drag and booster/MC rod adjustment

.

The new master cylinder came with a deep recess in the piston, just like the old one. But the slug from the old MC didn't fit into the hole. Ended up purchasing a new booster rod of the "long" variety, which is what's used with the deep recess/pocket MC. That was a 3 hour round trip. Got it back to the shop and found it would not fit into my booster! It was very close as the caliper showed and so I chucked it into a drill and rubbed the booster end on 20 grit sand like I was honing a cylinder then finished it with 800 grit. Took a bit but it fit.

Put the rear up on stands tonight and the plan is to bleed the brakes in the morning using pedal power then head out to the big show at TMS. I'm hoping for full braking power before the floor once again!!! If not...truck stays home.

Picture shows the original short booster rod and the one I installed after modification.
