[V6-12v] stopping problems

[The CyberPoet]

Check the bomb. Your car uses a high pressure reservior for brake 
assistance commonly nicknamed the bomb. To test the bomb, you drive the 
car, shut it off, then start pumping the brakes while counting the 
number of pumps. At some point, the peddle will fall and lose it's 
pressure, because the pressure reservior (the bomb) has been depleted. 
On a healthy bomb, that should occur around 40 pumps (+/- 8). A failing 
bomb will give up under 25 pumps or so.

You may also want to consider cleaning your rotors with a spray brake 
cleaner; if they picked up crud flung up from the road surface (such as 
transmission oil, diesel fuel, etc), especially during rains, the 
rotors might be coated with enough of a layer of contaminant to be 
problematic. Retest afterwards.

Finally, how long has it been since you flushed the lines? Brake fluid 
should be flushed every other year, or every year in especially high 
humidity locations.

Good Luck!
