Ron, You are THE MAN...


But, is there any way you could maybe post some LARGER pics?

Sure! I will next time.

I have found several other kits that look like they will work. I have ordered them. When i receive them i will post part #s. Kris, im going to rebuild all of my old cylinders, if you need one let me know. I should have 4 rebuilt within the next week.

if those works m sure you can make some quick cash. There aren't ANY available!

Here is a confirmed OReilly auto parts MCK33252 brake master rebuild kit $15.99, and these are readily available. Use your original hard parts.

Ok, I called O'Reilly and had them send a kit to my local store. I got it the same day. I removed the old plunger from my piston. To do it, I had to tear it off. It looks like the plunger is sandwiched in between the end of the piston.

I removed the new plunger from the new piston. I put it on my old piston but it doesn't have a "seat" like the new piston does so I am thinking it isn't going to work. It looks like it will just slide off (?)

I'd send pics but I lost my camera! Doooh!

My question to you is;

Is there a groove for the plunger to seat into on your old piston? Does it look like the new piston's groove?

My piston doesn't have a groove. It looks like the plunger was incorporated into the piston. (It is a Tokico.)

Mine is also a Tokico. This isn't the original piston, but the groove looks just like this one.

Thank you! Well, I am thinking I got a bum piston. Mine doesn't have a groove.

I am going to have a friend take a look at it and see if he can make it work. If not, I may take you up on purchasing one of your Master Cylinders.

Thank you for helping me with this

No problem, let me know. Just dont get rid of the old one. If you end up getting one of mine, i will want yours so i can rebuild it.
Could you post a pic of your piston so i can see whats going on? Thanks.

Good news and bad news:

BAD: I am stupid

GOOD: Once I "fully" removed the old plunger from my piston I realized there was a retaining ring around it to hold it inside the groove!
I installed the new plunger and it is a match. I need to clean out the Master and put it back together to test. I also have to wait for the cylinders to arrive. Feelin good now!

Thanks again!

Now I gotta get prepared for the Patrolgrimage...

I just received 6 master cylinder rebuild kits that I ordered for a 53-62 chevy corvette reybestos part# MK3, NAPA part #UP3. The kit looks perfect, This is the best rebuild kit that I have found so far. The piston is even the same length, but the piston doesn't have the hole in it for the Pedal rod. Looks like you could drill a hole in it. I will add some pics later. At least the piston is identical other than the hole, it will be a good alternative if anyone needs a new piston.

Does anyone have a suggestion on how to free a stuck piston? I have soaked it in PB oil for couple days with no avail. Any tricks out there to free it up? Thanks in advance.
