Pulsing feeling during braking

[santana]

I did a LOT of "replacing" a year or so ago when i thought i MIGHT have the seized caliper (which i did).

Had the front calipers replaced with A1 Carbone's and had all OEM rotors & pads installed simultaneously. (I was giving the 4Runner to my wife, so i wanted it to be 100% good to go.)

My only concern is this:

I feel my "booster" thats on the V8 braking system is kicking in TOO often. Im afraid this might have something to do witht he master cyl. or something to that effect. Im no mechanic, nor did i pay attention to any of the above for the first few years i owned the car. Its just that sometimes after i pump the brakes a few times, i hear the "buzz" from the booster and i feel the pressure in the brake pedal increase. If if at a stop and it kicks in, i can see the headlights dim ever-so-slightly when the booster kicks in.

Is this typical? Or maybe is there some warning signs I should be on the lookout for? The dealer techs that worked on the system when it was all flushed, replaced with OEM's said it all looked great.

probably better off starting a new topic

UPDATE:

So after some more research, I decided to take a closer look at the rear brakes. I found the solution to my problem! the driver's side rear caliper was "frozen".

I've read so many threads on here about the front calipers sticking/freezing up , i just assumed it was them. So moral of the story: I guess the rear calipers can freeze up too. I got a replacement from rockauto and I am back in business.
