Jul 21st, 2025 | | | | Joined: Sep 2008 Posts: 59 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2008 Posts: 59 | I pulled the front master cylinder off the 1957 Dodge firetruck and found about 1/2" of it had rust / heavy pitting in the bore of the cylinder from water sitting in the bottom of it. Truck is a 1957 Dodge K8-D8.
What I need help with is the part number of the master cylinder that the pedal pushes on. It is a different looking system with a front master cylinder, 2' piece of line to a rear master cylinder with booster. All the lines to the wheels run off the rear master cylinder.
Numbers I found on the cylinder are "EIS 39" piston diameter is 13/4", casting number P2 on the opposite side, "made in USA" but no other markings. Thanks for your help and I see a parts book in my future.

If you ever can't get new cylinders, or just want some to last forever, have the old ones stainless steel sleeved. DON'T mess with brass sleeves.
The guy to have stainless sleeve your cylinders is:
Mark "the machinist" Frappier
82 Mountianview St.
Agawam, MA 01001
413-789-4588, or 800-528-5235
You send him your bare, stripped, clean cylinders, and he sends them back with a perfect looking stainless insert.
You will still need to go to NAPA and get rebuild kits, or perhaps Jim Carter sells kits?

I called Mark he told me to contact Kanter Auto Parts, they had a complete cylinder in stock for less than repairing my existing cylinder. I am going to replace the entire cylinder since the existing one is an aftermarket replacement.

I would even give thought to having a brand new cylinder stainless steel sleeved..
Grigg | | | | | Joined: Mar 2004 Posts: 3,068 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 3,068 | The "rear" master with the "booster" I would think is just a hydro-vac. Most truck parts stores can get those. I just got one for my 48, but don't ask what I had to pay for it,

Joined: May 2005 Posts: 8,877 | White Post Restorations in White Post Va. can sleeve and rebuid your master,wheel cyls. and hydrovac unit.They do very good work. Do they use stainless steel sleeves? Brass sleeves are not as good as stainless, they can still corrode, and they wear more quickly than both cast iron and stainless. I have also heard that sometimes the rubber cups like to stick to the brass for some reason, and the brakes don't work, causing you to run into things... The above advice is from three different folks I worked with who each had years of first hand knoledge and experience with brass sleeved wheel cylinders.

Like I say in my business "Good service isn't cheap and cheap service isn't good !!

There are others that use the same materials that do them for much less money. When I was looking to have my MC done about 10 years ago they wanted over $200 just to put the sleeve in. At that time others were quoting less than half. I just wanted others to know they are not the only game in town, that's all...no harm intended. Mike B | | | | | Joined: Jan 2006 Posts: 586 Shop Shark | | Shop Shark Joined: Jan 2006 Posts: 586 | No harm Mike B !! After what I went through with the local "Apple People Company ", I would gladly pay White Post to do it right. Just MHO

From what I have seen and from several good friends who worked at WP a few years ago the quality of work on the brass sleeved cylinders was not the best, returns and rework were quite common, I haven't heard any updates though, perhaps they now use stainless and do better work???
Personally I would go to:
Mark "the machinist" Frappier
82 Mountianview St.
Agawam, MA 01001
413-789-4588, or 800-528-5235
He does outstanding work at very reasonable prices, often cheaper than you can get a new cylinder. I have never heard of or seen a less than perfect looking and functioning stainless steel sleeved cylinder from him.
The automotive restoration shop I worked for used him exclusively, and I have seen a fair number of cylinders sleeved by him. There were even a few times we had some cars come in with brass sleeved cylinders from WP that needed re-sleeving, Mark had no problems with that, and we ended up with a longer lasting better quality job, for less money I'm sure.
Having seen and experienced both the WP brass sleeved jobs, Mark's nicely stainless sleeved cylinders, and being a machinist myself; I highly recommend Mark's work.
