Brakes pedal slow to release....
Just that. I apply the brakes and the pedal is slow to release. The further down I push it the longer it takes to release. I replaced the master cylinder... didn't help. Someone said it might be the booster, or maybe even the caliper pistons. I took it to two shops and NO ONE could figure out what it is. My dad can't figure it out either and it's pissing him off.
What do you guys think? This is VERY annoying, and obviously can't be safe.

Could be the booster, calipers (doubtful though) or brake hoses.
When it is coming back up slowly does the car roll easily? If yes, then the hoses are not to blame (or calipers) but most likely the booster. If it acts like the brakes are still engaged then it is most likely the old rubber hoses.

Yeah, it feels like the brakes are still engaged. I guess I'll check the lines. Anything to look for? Are the only lines the ones from the A-arm area to the brakes, or are the other lines that need to be replaced?

its the flex lines between the chassis and the brake caliper..
replace all 3 lines... theres the 2 front ones, and the rear axle..
what happens is they rot from the inside out over time... imagine little dry rot hairs peeling off on the inside of the hose.
well, you push the pedal in, and they're pressed flat, letting fluid in the caliper... but when you let go, they get sucked into the way, making the fluid take forever to return.... like lil one way valves?
sound far fetched? its more common then you think... i thought it was wierd when i first heard it too.... my uncle ( a mechanic) told me about it.... heh.. i didnt believe him, did all the other stuff. then it turned out to be a $10 hose...... not to mention, its smart to replace the old rubber hose anyway...

Got the problem fixed. Turned out to be the rubber hoses.
Too bad I didn't find out soon enough: went for a trip to Va Beach and my brakes were acting up more than ever. Pulled into a parking lot, got out, and saw that my driver-side front wheel well had smoke pouring out
Yeah, the brake lines were bad, so with all the heat the caliper failed and permanantly stuck. It partially melted, the pad melted, and the rotor was TORE UP!!! Cost me $450 to fix (was out of town, so I couldn't do it myself)
But yeah, just thought I'd let everyone know so I could help future people out. If anyone has similar troubles, just do the lines right away. They're cheap, and it's very possible that's what is wrong.
