Need help with a few problems.

Lately it seems that my brake pedal is a bit soft. When you hit the brakes it feels like they slowly grab instead of being there. It maybe be me but it seems when the rpm's are high the brakes feel stiffer than at low rpm. I don't believe that the rpm would have any effect on the brake system. I was thinking it could be a few things but i am not sure. I was thinking that the drums maybe need adjusted in the rear or i was thinking that the master cyclinder maybe be goin (i hope not. I looked at the pads in the fron but there is still meat on them, could it the front rotors be gettin worn down ??? Also everynow and than when i go to hit the gas when i am crusing the car bogs for a second or so than takes off, i was thinking that the fuel filter may need changed ?

have you checked the fluid level? that'd be the first place to check...also, make sure the vacuum line is in place and not damaged.....

I've had the same problem with my enging bogging like that (especially after I've coasted down a hill with the car in gear...) Haven't yet been able to determine the cause. Let me know if you get anywhere with it.

The fluid is full. As far as a vaccum line i was thinking that could be a problem but when i checked the master cyclinder i couldn't really see a vaccum line. I'll look for the line tomorrow. Is there only one vaccum line ? And i am guessing that it comes right off or to the master cyclinder ?
