Progress on 55 Olds 98
Got the new steering box, master cylinder installed, new 2 piece rear main seal and oil pan gasket, turn signal switch and now rebuilding front suspension.

How big of a pain is it to remove the brake master cylinder? Mine is completely locked up from sitting so it needs a rebuild, at first glance it doesn't look like a lot of fun getting to the vacuum hoses or the hydraulic pipes.

It comes out from inside the car. Move the pedal back and there is a panel in the floorboard that the treadlevac attaches to that is bolted to the floorboard. Take the brake lines and the vacuum hose loose and then you can pull it out. If you don't have a factory shop manual you need to get one. It is the best thing you can buy for your car.

redoldsman is correct. You remove the pedal back and there is a floor board panel. It's a pain to remove the brake lines and vacuum hose but after you remove the bolts from inside, drop it (It's heavy) out the bottom of the car. And yes, the shop manual is a huge benefit.

Next is rebuilding the centerlink, replacing the tie rod ends, and wheel bearings. Then back up top to address the carburetor issues. I think there is a check valve for vacuum that I want to look at that could be causing some brake issues.

I vaguely remember doing one on my 56' super 88 but that was 20 years ago, I have a 1956 model shop manual, is it worth it to get one for the 1955 model year or are they close enough? The power steering gear is for sure different between 55 and 56, but otherwise they look very similar.

We disconnected the the lines, unbolted from panel and dropped out of bottom of car, reinstalled same way. Didn't wan't to take any chances of any fluid getting on carpet or inside of car. But maybe it's easier doing it redoldsman's way.

Some of the difference between the 55 and 56 brake system would be the location and design of the vacuum tank with the difference being that the 56 vacuum tank is under the hood passenger side and the tank on the 55 is under the left hand frame rail. There are quite a few small differences but using only one could cost you to take a wild goose chase ordering parts.... Tedd
