I know this is a strange question, but I have been unable to find an answer. I did a six speed swap on my car and ever since then my brakes have been extremely stiff. It is like they want to come out an inch or so more but the stopper area on the pedal assembly stops them from doing that. It is so bad that I cannot even put in my sensors that clip in there as it forces the brakes to be mashed.

Is there something I can adjust that will take pressure off of the brakes?

check to make sure something isn't binding and your pedals are mounted correctly. I really don't think there is anything to adjust but I could be wrong

did you mess with the brake booster hose?

No I did not and check the hose as well. Its weird; I mean the car stops on a dime but it is just extremely stiff. Maybe bleeding them will benefit me somehow.

air in the line makes the pedal spongy. a stiff pedal has to do with the brake booster.

There is no adjustment on discs. Drums are a diff story. Did all four of mine + front rotors last week.

Dang this is annoying me. I pulled the brake booster to see if I accidently drilled a hole or something in it when I drilled the hole for the master cylinder (I did a six speed swap) , but the thing looks fine. Before I go out and buy a brake booster is there a way to check mine?

Brake System Vacuum Source Test
Disconnect the engine vacuum hose from the vacuum brake booster check valve.
Install a vacuum gage to the engine vacuum hose.
Start the engine and allow the engine to idle until normal operating temperatures are reached.
Check to see if the engine vacuum reading is within the specified normal engine vacuum range. Specification
47-68 kPa (14-20 in Hg)

Turn the ignition OFF.
If the engine vacuum reading is within the specified normal range, proceed to step 10.
If the engine vacuum reading is NOT within the specified normal range, inspect the engine vacuum hose for the following conditions.
Tight connection to the engine
Collapse, deformation or contamination
Cracks, cuts, dry-rot
If any of these conditions were found with the engine vacuum hose, replace the hose, then repeat steps 2-4.
If none of these conditions were found with the engine vacuum hose, then there is an engine vacuum source problem, check the engine vacuum system.
Remove the vacuum brake booster check valve from the booster.
Install the check valve to the engine vacuum hose.
Install the vacuum gage to the check valve.
Start the engine and allow the engine to idle until normal operating temperatures are reached.
Turn the ignition OFF.
Check to see if the engine vacuum reading is maintained within the specified normal engine vacuum range. Specification
47-68 kPa (14-20 in Hg)

If the engine vacuum reading is maintained within the specified normal range, proceed to step 18.
If the engine vacuum reading is NOT maintained within the specified normal range, replace the brake booster check valve, then repeat steps 11-15.
Inspect the brake booster check valve grommet for the following conditions:
Firm connection to the vacuum brake booster
Deformation or contamination
Cracks, cuts, dry-rot
If any of these conditions were found with the check valve grommet, replace the grommet.
