Question about 2007 Chevrolet Equinox LS
Have replaced master cylinder brake booster both front calipers both front brake hoses and front brake pads
Have you checked GM, as well as repair shop data base
Bulletins for those brake issues?
Have you checked with professional scan tool in the
abs module for codes?
Who is replacing those parts & why?
Would seem more like an axle tone ring,wheel hub
tone wheel inside bearing hub,abs module needing to be reflashed
with an update or wheel speed sensors.

Testimonial: "booster and master cyl were replaced due to master cyl leaking into booster / all front brake parts replaced as a pm all parts are delco"
SOURCE: brake pedal dropping to floor
do u have the antilock brake bleeding tool? if not you will need to have the dealer bleed the brakes, the ABS control valve must be electricaly held open to bleed the brakes there of course is a special tool for this.

Try having the dealer flush and bleed your system. It is very hard to bleed ABS systems yourself and have safe brakes that still work afterward. Bleeding non-ABS brakes yourself is easy not the same for ABS brakes. Valving, sensors and what-not require a tech and the correct equipment in my opinion. You do it wrong and you could ruin your ABS system. Do that and see if they firm up. I replaced my brake shoes/pads at the same time all new everything in back, drums/springs everything and new rotors up front. then I had the chevy dealer flush, refill and bleed system. Stiffer pedal and brakes work better. Keep in mind the brakes on 99 Tahoes are inaedequate, require new rotors often, heat up and fade/glaze pads regularly. I replace my pads long before they wear down because they glaze up and start fading early. I'll rough em up once maybe, next time, new ones. Every two brake jobs, new rotors for me. Just how it is. They will stiffen a bit and work better but they will never be awesome brakes. Just how it is on 99 and earlier Tahoes. Hope it helps. Very important to bleed correctly though. I'll bleed my 83 Toyota 4x4 myself but not the Tahoe.

So long as the brake booster is working, test it by turning on the engine, press the brake pedal all the way down, then shut off engine keeping your foot on the brake pedal, if the pedal comes up slightly pushing against your foot then the booster IS working.
Did you BLEED the brakes??????
