Master Cylinder 1970 Power Disc
« on: July 25, 2010 - 08:06:23 PM »
hello,

i am needing some help in going to the part store to get the 'correct' master cylinder.  there are several choices, and i am not sure which one is the right one.  i am wanting the correct function, and correct look/style, but not necessarily the 1970 date coded correct part number.

thanks for the help!

What you've linked to will work I believe but if your looking for the OE '70 look

The one NAPA piece looks OK...not sure why the difference in bore size

The reservoir on the Rolik MC looks backwards too.  i checked out what the MC was for 1971 power disc MC, and got this:

does this look correct?

The Advanced unit looks good to me.  I can't look at an original right now or I would post a pic.  If you want a pic let me know.

with a bunch of views, and no replys, maybe i need to add some pics (NO!  not the uploader again!!!!)  ok, how about some links:

Autozone (I think this is the correct one, but it doesn't mention power brakes):
http://www.autozone.com/autozone/parts/Fenco-Reman-Master-Cylinder-Brake-System/1970-Plymouth-Barracuda/_/N-iqqquZ8kn47?counter=2&itemIdentifier=524071_0_0_5661%2C13121

AutoZone (This one mentions for power brakes, but for 426 too):
http://www.autozone.com/autozone/catalog/parts/partsShelf.jsp?itemIdentifier=706507_0_0_&skuDescription=FencoReman+/+MasterCylinder(BrakeSystem)&brandName=FencoReman&displayName=MasterCylinder(BrakeSystem)&skuDisplayName=FencoReman&categoryNValue=14499999&navValue=14400007&categoryDisplayName=MasterCylinder(BrakeSystem)&parentId=44-0&itemId=7-10&productId=706507

NAPA: (The reservoir looks backwards):
http://www.napaonline.com/Search/Detail.aspx?A=TSM101326_0170523645&An=599001+101970+50056+2056004

RockAuto (This one looks too tall, and backwards):
http://www.rockauto.com/catalog/moreinfo.php?pk=309076


1=Autozone= is not correct.

2=Autozone is correct.

1=NAPA correct style but should not have piston hold downs in mounting surface

Rock Autos looks correct, note the bolt going up thru the bottom of the reservoir....piston retaining bolt.

Bad NAPA link.  Try this one:
http://www.napaonline.com/Search/MultiImagePopup.aspx?ImageIndex=2&A=TSM101326_0170523645&An=599001+101970+50056+2056004


This one also has rear piston retainer which you can see is drilled and taped so it can be seen on front face of mounting pad when mounted.



What you've linked to will work I believe but if your looking for the OE '70 look

The one NAPA piece looks OK...not sure why the difference in bore size

Bill Roliks looks correct and is correct bore size.



The reservoir on the Rolik MC looks backwards too.  i checked out what the MC was for 1971 power disc MC, and got this:

http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Brake-Master-Cylinder-Cardone_5350166-P_230_R|GRPBRHYAMS_1289062779___

This is not correct.

You have 2 different types in the links, the one you are after is 2.5 inches wide and 4 inches deep.
Other one in links is 3 inches wide and 3.25 inches deep.
Both will work but if you have original brake lines and buy the shallower one you will have to "stretch" your lines to hook it up or buy new ones.
It has a 1 inch bore.
Whew, been watchin this thread but I'm a one finger keyboard pecker and don't have a lot of time to post and thought someone else would nail it....lots of knowledgeable people here.
If you order one from Bill you will get what you're after only it will not have the Chrysler casting number and date coding and vendor info stamped in it.
If you order from any of the parts stores you're most likely get the wrong one you have pictured because it will bolt up and work.
Correct cores are getting real hard to find, I know because I have been  restoring/rebuilding them for about 25 years and they used to be plentiful.

Good Thread. Does Mopar still sell Master Cylinders, or long gone?

The units bought at NAPA etc. have a snout on the front. These are units generally found on B Bodies. They'll work but they aren't correct in appearance.

Cardone 10-1515

http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_x_5350166-P_x_x?cm_mmc=CSE-_-Google-_-VALUE3-_-VALUE4&ci_src=14110944&ci_sku=5350166

it took me 6 tries (4 at advance, and 2 at the local parts store, (where i finally got the right one.)) to get the correct appearance MC.

i just had to keep trying until i finally got the right one.
