S52 swap. previously a m20 auto. Moved booster 1/2 inch. Used 328ijunkies welded clevis & retained the same brake adjustment or close to it. sat outside for 3 months covered. When swap was finished in october, bled brakes thoroughly. Pedal would almost be immediate hard and you could feel the vehicle slow down on its own. I assumed the adjustment was way off so i messed with the adjustment and now the brake pedal sits is where clevis & the rod goes together. No issues since. Planned on changing the master just because and was looking into a e32 master.
Last month, i did my front brakes & it was extremely hard to push the piston back into the caliper as i had to open the bleeder valve to do so. I then looked into caliper rebuild kits & replacing calipers. At the time my schedule did not get a chance to do but because after the drive vehicle the didnt give me issues after the brake job.
Present day, pedal became hard and same issued occured. I would have to pull up on the pedal and it would free up the rotors. Let me also add at idle the booster would hiss & when i push down it would go away and then hiss again. Now if you apply the basic common sense it would be the adjustment is still off. For me im at a loss what to do first but i know i should change the booster & the master & look into the calipers. I guess im looking for a complex answer on why everything is acting the way it is. If you were to jump into the vehicle & drive it now it would do the following.
-Hiss at idle.
-Brake pedal be spongey but effort is average
-When the calipers stiff pedal be hard at resting position to when you press it.
- When i pull up the pedal, it releases & everything is okay from that point.
When i read about adjustment of the brake pedal it can be set for the sensitivity of pedal. So if its inconsistent where does that put me at?
In what order should i go as far as repairing this issue?
I think about getting a smaller booster & a new master but i have a heard from some close people they feel the smaller booster isnt enough, then again people track with that booster and have no issues. Thanks in advance
