So, I decided to upgrade the brake booster to a '93 Cobra booster to see if it'd fix my weak brakes. Weak, as in, I can't lock up the brakes at any speed.
I've had weak brakes in my car since I bought it. It's pretty modified, so here's a quick background: 5.0 with HCI, Baer sport 4-wheel disc brake upgrade, SN95 master cylinder, modified combination valve, adj prop valve to rear.
What I've checked so far: pads/rotors are in good shape. Engine idles with about 12mmHg. Can't identify any significant vacuum leaks. I put a line pressure gauge on the front and rear calipers. With the engine running and after a few revs to power up the booster, I could only push about 1100psi front and rear when mashing the pedal. The stock booster can hold at least 20mmHg when using a hand vacuum pump.
I went the route of the booster upgrade to see if it'd counteract the low vacuum, as some research pointed out some people were able to get normal brake capacity after this upgrade.
Now the problem:
I got the booster bolted in. However, the brake switch now gets in the way of the steering column brace and wants to crush the connector on release of the pedal. I tried getting a SN95 brake switch, since the connector mounts to the side, instead of behind. It, too, gets in the way of the brace in a different spot.
What could I be missing? Do I need a spacer on the booster?
