Hey,
I’m fixing up my 1991 SC and it should be roadworthy soon, but I am a little concerned about the brakes. Sometimes, the car can be on or running for 1-2 minutes before the brake booster begins to charge. Now, to be fair, it only did this a few times after not starting the car for like 4-5 months and it seems to come on right away ever since. However, if I turn the car on for the first time in a day, it takes almost a full minute for it to charge. If I turn off the car and turn it on again 30 minutes later, it takes maybe 15 seconds to charge (but this seems long if the car just got charged less than an hour ago).
This seems weird to me because my 1990 brake booster would usually only charge 15-30 seconds for the first time in a day and only charge for maybe 10 seconds if I restarted the car 2 hours later. Im estimating the times, but it really seems like my 1991 spends a lot more time charging its brakes than my 1990, even when it seems like the brakes were just charged a short while ago. The accumulator ball was new in 2013 and the car has not been driven since 2015 (I do start the engine every couple of months and move it up and down the driveway).
I’ve driven my 1990 SC a lot and it’s entire brake booster was rebuilt by Supercoupe Performance, so it seems like a good baseline for what a healthy brake booster should act like. Am I leaking pressure or is perhaps a sensor worn out? Just wondering if anyone else had this same issue/concern.
