Replace master cylinder and bleed the brakes. Do not use synthetic fluid as the ABS does not work well with it. I like Ford high performance fluid. Twice the boiling point of regular brake fluid.
First and foremost, thank you. Second -- well, crap. The car has 14K miles on it. Is that truly an indication of a permanent MC failure or is it your opinion that starting with the MC replacement is the easiest/most likely best path to resolving the underlying issue?Replace master cylinder and bleed the brakes.

Thanks for the detail. It is definitely in the plans to hit the road course in the future, however I haven't fully sorted out my brake mod plans for that yet (pads, upgrading to stainless lines, fluids, etc.). The Castrol SRF looks like the absolute top tier option for a road course car, however I may stay a little lower on the cost in attempting to see if fresh fluid and a bleed resolve the current issue.You can try just bleeding the brakes with a quality fluid first and see if that does the trick before diving into a brake master replacement. Motul is a great option, RBF600 will be more than adequate in a street car but if you want to hit a road course with it I would be looking for Castrol SRF.
Thanks for this additional detail. Let's see -- 30 year old Corvette equals LS1 C5. My track car is a 2002 Camaro SS (same LS1 platform).Motul is great too. I have had lots of old cars with leaky master cylinders. The seals fail internally and bleed off pressure like you describe. My Corvette is 30 years old and it did exactly as you describe. Check out rock auto and get a master cylinder and some fluid from the local dealership. Cracks me up when I go into Ford and the guys don't know what they have. They try to sell the regular fluid in the blue label bottle. The High Performance fluid is red label. They have both DOT 3 and DOT 4 now.
Yes, bought the AC Delco/OEM one off of Rock Auto for $92 + shipping. I didn't have the time to get the work done myself so had a local hot rod shop do the work and it was $150 in labor. Already had a new bottle of ATE DOT 4 fluid at home so "all in" this was probably a $270 fix. Definitely one of those rare repairs where the cost came in substantially lower than what I was expecting.Did you buy OEM master cylinder or…. Figure I should get one now and avoid the pain in the future…
Awesome! If you aren't already on LS1Tech, it's a great place to tackle any issues that arise on the F-body. The 10-bolt rears are a huge weak link so limit the sticky tires unless you plan to upgrade it or deal with the regular rebuilds. I fought with it for years and never dumped the clutch at high RPM at the track for fear of shredding another one -- finally bit the bullet on a Dana S60 and it's been a complete gamechanger in the enjoyment I get from the car. Aside from the rear, the issues they have are relatively minor and typically cheap to fix. My 02 SS feels like a tin can compared to the CTS-V. It's lightweight, irreverently loud and you smell like fuel when you get out, but it sure is fun on the track. Enjoy yours!!I got a good deal on a used 2002 Camaro SS at an online auction because I used Live Video Streaming, so I can see the condition of the car. For now everything is perfect, but I am already preparing for the future issues. Information about fluid is very useful, thanks
None at all so far. As I would expect most on this site would do, once the brakes were "fixed" I felt obligated to confirm there were no lingering issues. Passed on all tests. The weather around here hasn't been great so I haven't had the car out long enough to brake from higher speeds and really get some heat in the system, however that will come soon enough.Good information here. Before I parked my car, I had noticed the brake pedal slowly creeping towards the floor at prolonged stops.
I have planned to replace the brake lines and flush the system, but I guess it couldn't hurt to include a new MC. My car has very high miles.
Did you have any subsequent ABS issues after bleeding the brakes?
