I have never had problems with brakes at Laguna.  I don't know exactly why,
but I'm easy on brakes in general.  Here are a few things that are probably
obvious to you, but worth mentioning:

1) I use Performance Friction pads.  They don't have clamps, so they don't
cling on to the pistons and boil the fluid.  They rattle like hell, but
that's the price you pay.

2) Start your braking sooner and stay on it longer instead of jumping on the
breaks at the last moment.

3) Spend 25% of your braking time getting on, 25% getting off and 50% at the
threshold.  That makes for very smooth braking.  You use carry some of your
last 25% into turn 2.

4) Get on the brakes right before the crest of the hill before the
corkscrew, lift at the crest and back on the brakes before the turn.  This
keeps the ABS from kicking in.

5) Don't brake too much in 10.  It's not as bad as you think.  It's an
optical illusion. :)  It's an on-camber turn.  The tendency is to break too
much, then compensate by jumping on the gas.  Easy on the brakes, then
steady increase of throttle through the turn (this is a gem I picked up from
Steve Dinan and it's yours for free).
