YACT: 93 Honda Accord Disc Brakes

I changed my front disc brakes on my accord and now they dont work...lol. Whenever I press down on the brake pedal, it feels like there's almost no force pushing it back. Does anyone have experience with car brakes? Tell me where I messed up?
 
Yeah I bought a 32 oz can of dot 3 brake fluid and put some in already. I also bled the calipers too just in case. I only changed the pads and everything was working fine before I worked on it. Now I'm stuck with a car with no brakes and I have to go to the airport to pick up my gf for thxgiving tomorrow :frown:
 
Sounds like they were bled incorrectly, and there is now air in the caliper/lines, which is compressing and giving you no stopping power. (this is assuming the pedal goes to the floor)

You did have the rotors turned right?
 
Your first mistake was working on your brakes and not knowing what you were doing.

Your second mistake was coming to ATOT to find an answer to your problem

Your third mistake will be to try to rectify what you have already fvcked up and/or drive the car in it's current condition.

Take the damn car to a qualified mechanic and get the brakes fixed right. You, as a total noob, had no right to endanger your life and the lives of others without being being qualified to know what you are doing. Brakes are not to be trifiled with.
 
Did you just bleed the calipers? There exists your problem. You bleed all four wheels or you'll end up with air in the lines. Bleed the driver rear, then passenger front, passenger rear and finally driver front. That should do the trick.
 
Yeah I kinda felt like I messed up on the bleeding too, but wasn't sure if that was what was causing the problem. No, I didnt turn the rotors...I didnt know I was supposed to do that for a brake pad change, how do you do that? And what's the purpose of it? Btw, Thx for the help guys.

Part of the problem is that the Rotors were not turned. Turning the rotors is a slang term. Basicly what it means is the rotors are set up on a metal lathe, and the surface is cut true and flat (there is a pattern actually. rotors can be too smooth)

You now have new pads that are perfectly flat (or you did anyway) but your rotor has groves, and is likely worn at a very slight angle. This means only 30% or less of your pad is actually touching the surface of the rotor. (30% number pulled from my ass because I don't remember the actual number. it is well less than 100% though) The braking effectiveness will imporve slightly over time as the pad wears to fit the groves on the rotor, which is going to make the groves in the rotor worse, which may make it so your rotor can not be turned without going below the minimum allowed thickness for your car, in which case you need new rotors. (they are not as expensive as you may think though)

It is extreamly dificult to bleed the brakes by yourslef. (nearly impossible without special tools or a kit specifcly for this purpose)

When you bleed the brakes, first do the master cyl (you should not have to do this unless your tank ran dry) then start at the farthest wheel from the master cyl, and work closer. This usually means passenger rear, driver rear, passenger front, driver front.

Not exactly. The way the proportioning valve is for our cars the front driver and rear passenger brakes are linked and the passenger front and driver rear brakes are linked. That's why you do them in pairs instead of doing the rear brakes and then the front brakes (as Evadman suggested)

Is this manual online, or do you have a hard copy?
I would like to read this part.

Hard Copy. I do all my own work on my car.

I went into my vast library of owners manuals (I have a ton in PDF format) with the express purpose of making you eat your words NutBucket. I looked in the Mid and late 90's ownes manuals for the Accords & Civic's. They are all exactly the same.

You are ALMOST right. It is actually Passenger Rear, Driver front, Driver Rear, Passenger Front.

That is the most fvcked up order I have ever seen. HappyPuppy was correct in the warning though, because on 99% of cars, it is done furthest from the master cyl. I wonder if Roger knew this, because I would have argued with you on this all day long.

I appologize.

Why don't you STFU instead? You just keep sh*tting in this thread without actually posting something useful. Yeah like he's going to get his car to a mechanic when his brakes don't work dumbass.
