Master cylinder question

[camaroman9]

What is everyone using for master cylinders? I'm getting ready to convert to manual brakes on my car, but I don't know whether to buy wilwood or another brand. I know the wilwood mc comes with the rod for the pedal. What does everyone use to build their rods when using a master cylinder that doesn't come with the rod?

I used a grade 8 bolt on mine, just cut the head off and ground a radius in it to fit the M/C. Sam should be able to fix you up with a Dodge Master Cyl. Check his special shelf...

The only thing that sucks about getting one from him is they are reman and don't come with reservoir.

Here's the 1 1/8" Model I have on my car;

Carquest BPR20-1860
NAPA 39178
O'Reilly MC98894

Pretty sure I got it at O'Reilly's, new with resevior. Looks just like the picture on the M/C Page

FYI the pn changed at oriellys on that master cylinder. It is now mc98895

Thanks for the info, I've updated the page.

a guy gave me one just like this, mounted in top holes and put tin around to fill in hole, used stock rod, works great

Is this the correct MS to use with a disk front and rear combo?

Thanks.

Yep

I ordered that NAPA number last week it was cast iron with the plastic reservoir like the aluminum Dodge cylinders I always saw on the little k cars. It kind of shocked me, it must be one of those cost cutting measures those companies do. Just an fyi if it's been a while since you bought one.

Can you take it back? Maybe something has changed as at one time that was an Aluminum PN I believe.

You might try O'Reilly's

Yeah I sent it back. I'm in VA and don't think I've seen an O'Reilly's around here. I have a repair shop with accounts and access to the parts storeservers. I looked the Carquest number up on their server, it had one picture of a master cylinder that was aluminum without the resevoir and another of the same item that Napa had (at least it looked like it) both under the same part number. I ordered a Wilwood, it was easier. I wish the Napa part was right it was all of $31.00.

When using one of these master cylinders do you still use the stock proportioning valve? If you get rid of the stock proportioning valve what do you use to split the brake lines to each front wheel?

[John_Heard]

Most get rid of the OEM prop/distribution valve body and use a wilwood, or other brand adjustable prop valve in the line to the FRONT brakes. You just use a brass T block to split the line up front, or you could use a AN style "T" if you're wanting to use AN style fittings.

The reason you'll want a prop valve in the front is the skinny front tires will be the ones that want to lock up well before the big sticky tires in the rear.

Ok, that makes sense. Thank you very much!
