Default brakes not effective

My 93LS seems to be experiencing really poor brakes. I realized it because i drove my friend's 91LS today. And I realized that the difference between his brakes and mine are night and day. his are really responsive with a very firm pedal.
Mine, spongy pedal, excessive pedal travel, barking distance twice as much as his, takes twice as much force to brake as it did on my friend's 91.
In the past 6 months the following have been done on the barking system :
1. brake booster replaced
2. Master cylinder replaced
3. All rotors checked.
All the above has been done by the dealer. but the brakes still arent anything compared to the other LS's i've driven.
any thoughts / ideas would be appreciated !

Default spongy pedal & excessive pedal travel?

These two problems are usually caused by 1) air in system and/or bad seals in master cylinder. You can either bring your car back to the dealer and complaint about it or take the car to another garage. There is nothing complicate or difficult about the problems that you experienced. Good luck and cheers.

Master cylinder has been replaced by new one. no changes were found even after putting the new one in.
brake system has been bled and no air is in it at the moment.
any other suggestions.... ?

I found just the opposite!

My 90 LS has the crappiest brakes I've ever used.

I drove a 93' the ohter day and was astounded at how much better they were!

One of the Lexus tech people actually told me that the small 1st gen brakes usually work better then 93+. I want to replace them anyway though.

Hmmm...I thought the brakes were upgraded to dual piston calipers in 93...I wonder why the tech believes them to be inferior...
