Where is the refill plug for the master cylinder located? I've got a Holiday 88 with power brakes cannot find it anyplace.

I moved your post to it's own thread. The thread you resurrected was originally from 2013 and the person with that 1955 hasn't been on the site since 2021.

 

 

Thank You Joe

 

I am not sure about a 56 but on a 54 it is down at the bottom of the firewall by the steering column.

 

Thank You For Your Service: Does it have a dipstick instead of a plug? I have the Moraine Power Steering unit.

 

It is a actually a screw in plug with a dipstick on it. It should have a triangle wire (heavy) **** on the top used to screw it out of the master cylinder. Then the dipstick is on the bottom of the plug. It is kind of a pain. You will need a transmission funnel to add brake fluid. I hope this makes some sense.

 

OKAY That's it!! I tried to turn it counterclockwise, but my old knuckles are not strong enough.

Didn't want to break anything just out of curiosity....

I served on Okinawa 68-70 with the Corps of Engineers supporting the NIKE-Hawk missile batteries serving as air defense for KADENA AFB.
Every morning the 52's would get airborne with a full rack of ordinance and return every evening much lighter.
Again, thanks for doing your part when our country called!

I'm not sure, but I think it only has the triangle wire for removal if it is an AC car. Otherwise, it is the standard spade type with dip stick on the bottom. It lies near the steering box on the left... Tedd

 

Interesting on the triangle wire Tedd. My 54 had teh triangle wire and of course it was not a factory air car. But when they get to be that old, all bets are off. I had it rebuilt by Karps and maybe he changed it.

 

As I remember, the Bendix had the triangular dipstick and the Moraine did not. In any event, as Glenn said, it's a pain to add fluid. I found this Lab wash bottle that works great. It's also called a "tattoo wash bottle".

[Thank You all

 

Good idea Chuck. Just a reminder to keep brake fluid off the paint. It will remove paint quicker than point remover.

All: I used a large Allen wrench for leverage and was able to get the Triangle large wire cap/plug to rotate counterclockwise.
Thanks for all your help, this my first Rocket 88 powered vehicle and everything seems a tad over engineered! (Like a MB 190 I had once)
Good thing I checked there was no fluid indicating on the short dip stick rod (it seems to have a small "L" engraved near the end)
I bought a miniature funnel at the local hardware store and was able to fill the reservoir enough to register.

One recommendation if you haven't already done this Clutch. Go on ebay and buy you an original factory shop manual. Do not get the reprints of CD version. You want one with some greasy thumbprints on it. Shop them because the prices will vary considerably. Here I one I found.

Thanks I will get one, do you know if there are CHILTONS out there ??

 

I hsve never looked for a Chilton's. With the FSM you will not need a Chilton's.

 

I agree- I've never used a Chilton's on my '56.

 

In my opinion the 1956 Oldsmobile Shop Manual is far better than the Chilton for most situations. If you get the Olds manual, start reading on page 7-6 (194). It will tell you more than you will need to know about your power brakes.

 

Thanks Ozzie:

Yes the CHILTONS covers all automobile makes, very general in its instructions....

 

Chilton's were good when you worked on lots of different cars and needed to do normal repairs on them. Such as a tune up, or brakes. If you own your own car and do extensive work it's pretty useless. Chassis Service Manual from the factory is the way to go.
