i recently discovered that when i am in stop and go traffic, my pedal gets harder. and if my foot pumps the brake, it creates a harder pedal feel. is that due to the braided lines i have or the brembo calipers? i have come to a decision and it is either the master cylinder or i need to bleed my lines. anyone have any ideas what it could be?
p.s. i searched.

This is sooo JDM... it even said so on ebay.
Well, about the pumping...that's normal, to a certain degree. Any car with power assisted brakes will allow you to increase the pressure in the break lines by pumping the the pedal. I can do the same thing in my '93 with really old breaks. Pumping quickly and lightly will make the pedal very tough to press. If it's too difficult to press during normal driving (without pumping), though, it could be too much assist - hope that helps.
^if they are new pads and brakes, then its goin to be a little stiff.. also, where did you get your brembos, do you have any pics of them
theyre stock size, crossdrilled and slotted. they have the brembo logo on the actual rotor i got them for like 90-110 heres the number if the place....it was near me in miami. 1-954-445-6273. i believe it was irotors.com or i-rotors.com something like that.

i know it used to do it, but its alot more than before to the point where its stiff until about a second then it loosens up

If the master cylinder is failing then typically the pedal feel will get really soft. I had a master cylinder go out on a 71 impala once (3400 pound 4 door boat)...that was not a pretty sight. Scared the hell out of the passenger when I told him I was resting the brake pedal against the firewall lol.

so its one of those things that you most difenetly know when it goes not gets worse as time goes on.

When it goes completely bad, yeah, you'll know it. In all likelyhood you'll notice a significant drop in brake pressure feel before it fails completely, mine blew a seal so I had no warning but the damn thing was over 20 years old too.
It sound that nobody realy knows whats going on. Lets do some "research" on the problem. If the car is friven in stop&go traffic eg. peak hour traffic the brakes become hard to press, so in stop&go traffic the engine don't realy get the revs up - Now lets do a simple test with a car thats got no brake problems , after driving the car switch the engine off and press on the brake pedal several times don't the brakes become harder as in this case(problem reported)?
The only reson for the brake pedal to become harder is the lack of vacuum when the engine is switch off and if my teory is corect if I'm saying our friend with the "hard" brake pedal got a vacuum leack someware between the brake booster and the engine.
That is why in stop&go traffic the brake pedal becomes hard and when the car gets driven in a normal way the brake pedal feels beter(softer , normal). The problem will get worse with the vacuum leak becoming worse.
So check for a vacuum leak in the brake / booster system.
Hope this will help anybody that gets this problem.
