Default Master Cylinder conversion

This post will interest only those installing big brakes on an early Impreza.

After installing the StopTech BBK on my 93L, I discovered the 15/16 size master cyclinder on the L was not able to hold enough brake fluid to keep the petal from going almost all the way to the floor when stopping.

After a search on this forum, I found Stimpy and Legacy777 (maybe others too) had solved this problem by installing a master cyclinder from a specific mid-90's SVX. http://forums.nasioc.com/forums/show...aster+cylinder

Mucho thanks to these guys. The only problem is that Stimpy bought the last new MC on earth (I verified this) and the recycle people only understand ABS master cyclinders, which has two ports.

So, after a lot of web surfing, I found a new non-Subaru manufacturer that makes such a MC. You have probably heard of AC Delco. Even so, my car has the hill holder, which requires three MC ports, not four. I plugged one port by cutting a new brake line (AutoZone, $2.90) , crimping and soldering the open end. This screws into the unused port and seals it completely.

I have tried to post pics, maybe it will work. Which BTW seems harder than installing the MC. It is a lot easier on other boards.

Thumbs up any part number for the ac delco part?

great find,

and a nice informative heads-up for those of us seeking the same mod parts.

have you the part number that ac delco uses to log this specific MC? i ask because i'm seeking a pair also. i had a miss on one of these when i picked up one from ebay for $10. it was a two port 1&1/16. nice deal though.

I found the piece HERE .

Open RockAuto, click on start, then choose the third (pink) tab titled "Click Here For Part Search". Key in part # 18M697. This takes you directly to the correct master cyclinder.

Or, click on the first tab (white) named "Part Catalog" and follow through the titles for Subaru to the master cyclinder choices for a 1994 SVX without ABS. This takes you to the same place, but if you are the type to verify stuff like I am, this way lists all the choices. Now you can assure youeself you are getting the correct MC. You will be suprized how many choices of MC's there are for Subaru SVX MY1994.

Also please note I wouldn't know who Rock Auto was if they took me to lunch. This is where I found the part and they did a good job. No other connection, so look elsewhere if you have a favorite source.

Here are some better pics.

EDIT: I am incredible unskilled at posting pictures, but here they are!
