Mikes Tip For The Day. Adding A Cobra Brake Booster.

Since this has been revived, and since I have driven the car about 350 miles now,....I do have an update.

While I agree my statement was ambiguous, and is open to interpretation based on actual preference, I was comparing the existing booster to nothing as an alternative.

I had manual brakes in the red car. That equates to "nothing".

So then,...here's the deal:

You cannot "lock" the brakes in this car, nor is the pedal "hard as a brick". I said that my brake pedal feel is very good,...and doesn't require any additional effort to get the car to stop. Now, stopping like a 2005 GTO,.or any late model.........not even close. That can be due to several factors however, none of which I have explored fully yet, but can be summed up in several possible scenarios:

#1. The booster is inadequate, and cannot assist in moving the required fluid to the four disc's currently on my car.(SN 95/ Cobra stuff on all four corners, Cobra MC, adj prop valve)
#1a. The booster is OLD...this is 38 yr old factory installed unit.
#2. I haven't got my brake bias adjuster dialed in to properly proportion brake pressure, and I'm giving the rear brakes too much bias...(unlikely, because I should be able to at least lock the rears instead,....but they are 315's after all,...and that is a giant amount of rolling mass for a 12" rotor to try and lock up...) Maybe I should throw the stock 185/15's back on and try it?
#3. The 6.5 qts of engine oil that I decided to apply to the entire underside of my car (to include the driver side front/rear brake systems especially) as a result of a -10 oil line failure, has fouled those two wheels, and now I have a "less than" with regard to optimal friction application when the pad meets the rotor. This is in spite of the fact that I thoroughly cleaned those two surfaces after my personal Exxon Valdeez moment **

** No indigenous wildlife was injured during this oil spill, and great care was taken to properly contain this enviro-hazard.
Our people labor tirelessly when my car decides to sht itself, and all necessary steps are taken to return our roads, and parking lots back to their normal, disgusting surface quality in the exact same condition that they were prior to being coated in brand new, synthetic 5w30 Syntec.

In hindsight,..The brake system seems good enough for a daily driver, but lacks the stopping power required for an absolute emergency panic stop, or if you wanted to track the car. It's not 100% definitive yet, I haven't even checked that the brakes are optimally bled, optimally biased, or that they are somehow compromised ...I've been too focused on trying to spin the tires, not stop them.
