Good evening all,
I have a problem I'm trying to solve and looking for help, particularly if you have an Areoforce gauge(s) so you can read the psi. I replaced my brake master cylinder with a Terflex big bore master cylinder, replaced the Booster (master cylinder was leaking into it) and I have new SS brake lines. After install my brakes light were stuck on after I parked a few times. This lead me to look at the brake psi. I found that my brake psi, would stay at 5-9 psi, but would sometimes spike to 16, 23, 30 and even 33 psi. I found out that when the brake pressure was high the brake lights were "stuck" on. The brake pedal was not fully resetting, the booster was removed and adjusted to reset the pedal. High psi and brake lights still on. The brake light switch was reset, it was a little better, but still happening. Replaced the switch, still happening. I am thinking that the high psi means brakes are slightly applied. Auto shop swears that the calipers, master and booster are all working properly.
I readjusted the new switch and I think I "fixed" the brake lights staying on, but not the psi.....
1. Does anyone have a gauge to read brake psi? I want to compare readings, I never looked at psi before my brake issues. Maybe the jumpy psi is normal?
2. Any ideas what else could be happening?
I'm $800 into the install and attempts to fix the issues and I'm out of ideas.
