Ok so SF isn't really helping me. I'll just copy and paste most of the information.

The first time was when I was going to the San Jose meet on the 22nd. I was cruising down the hwy, then all of a sudden my car felt really sluggish. I'm supposed to be going alot faster at 3k in 5th...so I down shifted to 4, and still no difference. So I pulled over on the street I exit to get to the complex where everyone is at, but I wasn't there. I get out the car, my car over heats and starts spewing out shit from the overflow tank, my brakes are SMOKING and yeah. I called David (driftedmk3) and he asks a few people and they tell me to pull my abs relay. So I do. and my brakes work again.

Now today, I was coming home from work. I hit a stop light, my car feels hella sluggish. I think to my self...not again. so I pull into the church parking lot near me and it was locked. No smoke though. No over heating. I pull the relay, still doesn't work. My Master cylinder works(depressed the pedal, stays there) It has fluid in it. My brake lines are good, no leaking. My calipers are fairly new, about a year and a half old. Help the poopra

Update...

My brake booster is good! I pulled the vacuum line on it and the booster still sucks in like like it should. BTW, let me clarify when I depress the pedal. What happens is when I press down on the pedal, it goes down to some point...and it stays there. once I take my foot off, it comes back come. Sorry for the misconception. Now it's wierd, because last night I started it, to get it up my drive way so I can jack it up, but my brakes worked again. All the times this happened to my car, have been when it was hot. Does that have anything to do with it?

BTW I know how it feels to have my brakes shot. Happened to my beater, '93 Accord. The brake pedal went down so quick, and wouldn't come back up. I had to brake with my e brake -_-.

Update

Damn it they locked again today when I went to go to the shop to have my shit checked out.

The dood said it was either my preportioning(sp?) Valve or...I forgot which one he said it was... my calipers or brake pads.

update

I brought it to my friends shop, but they didn't get a good chance to check it since they were SWAMPED with cars. So for now he said I should order some rotors and pads, possibly some calipers. BTW, they locked on the way there, and when I was in the parking lot...all 4 locked and it wouldn't move...so he just loosened the master cylinder line. So for parts...I'm thinking Ebay slotted rotors and endless brake pads? Any suggestions?




Do you guys think you would be able to help me?
