Did you break a steel line or a rubber hose?
Check eveything out, while you are at it?

I've had the same thing happen.
Luckily it was a rear hose and I limped home on my front brakes.
Keep us posted on your progress.

start with the Master Cylinder and booster though... then check the rubber lines, wheel cylinders and last the steel lines.

There are pre-bent systems (inlinetube) and some guys love them while other cuss at them... $200 for a stainless system with ends is hard to beat though.

I just got my set from inline tube yesterday. Had them installed in a couple of hours. They're pretty nice.

When I replaced mine on my 64 I just took the old one off and bent the new one to match! Bought my lines in pieces from Napa. New shoes,wheel cylinders and brake lines with a dual Pot MC made a HE-- of a difference Stops Now! OH buy the way Thanks t o the forum on help,all my questions were on line already

I bend my own too, but I buy the 25 foot roll and cut it to fit exactly. I have recently found that AutoZone carries the nickle/copper alloy tube. WOW that stuff is nice!

Slave cylinder? Me thinks you are using clutch terminology. Brakes have Master Cylinders, calipers, and wheel cylinders. ;) Long straight line, easy fix.

Re: this sucks lost my brakes at a stop light
 
what i was saying was i replaced both as the slave cylinder was apart of the master cylinder

Um, no. Some where there is a terminology break down. The brake system has no slave cylinder. Was it a vacuum booster/MC combo? Or MC/Proportioning valve combo? Or better, pics.

On drum brakes, the brake cylinder in the drums are often referred to as a slave cylinder. In hydraulic systems, regardless of application, master and slave names are commonly used. Master is the cylinder that applies pressure to the system and any cylinders that are moved by this pressure would be slave cylinders.

In auto applications, you commonly hear slave being used for a clutch system but it would be a correct term for the wheel cylinders, just not common.

Not common at all, and would confuse every look up chart or program out there. Of course that would be a good excuse to cuss the box store for giving you the wrong part.

In shop class i learned it referred to as both slave cylinder and wheel cylinder. Hence the term "master cylinder" it was the larger of the brake cylinders and the smaller was the "wheel" cylinder or slave cylinder.

Guess I go back far enough... before they had computers to "look up parts". Old school days of a real person with a real book in hand. Miss those days as I never had to give them year, make, model, engine size, transmission, A/C, power whatever, color, where I bought it, etc., etc. to look up a damn part. Used to just go in and ask for a part. Now I have to "make up" all this info to get a common part that was used for decades across the whole GM line. Oh well... that's progress... :uhmk:

The slave cylinder reservoir is apart of the master cylinder one side goes to the brakes and the other goes to slave cylinder. Here is a picture of it
