    Brake Bleed Sequence

    Does anyone know the correct bleeding sequence for an '03 Corolla - without ABS?

    Do the Corolla brakes all feel crappy? I mean, like GM brakes. Lousy pedal feel, etc. This is my wife's car, she bought it used with 9K miles. Brakes have always felt this way. But it has ~ 45K miles on it, and I decided it's probably time to change the brake fluid.

    TIA.

    Mine are fine. You could have water or air in your brake lines.
    Bleeding and changing your brake fluid is easy but requires 2 people. Pop the hood and locate the brake fluid reservoir. Uncap the reservoir and have a bottle of brake fluid at hand. Fill it up Jack the car up and remove the front wheels. Locate the bleeder valve for the 2 front disc brakes. Have one person sitting in the driver's seat. [[[Have the person in the driver's seat pump the brake about 10 times and hold it down as far as it can go. Undo the bleeder valve. The built up pressure from pumping the brakes will force the fluid out violently so be prepared. It could get messy. I would not recommend wearing your Sunday's best. When the flow of the stream from the bleeder valve has subsided but not stopped, close the valve. Remember, the brake pedal must still be depressed this whole time. After the valve is closed however, the person inside the car may let up the brake pedal. Refill the brake fluid reservoir back the the fill line.]]] Repeat the section in triple brackets about 2 times. That should be it. Good luck. Hope this helps.

    Thanks for the write-up. I've got a MityVac, which makes it a lot simpler (and one-man), aside from squatting down to get to the bleeders. Don't even have to remove the wheels.

    I already bled/changed fluid this weekend, but I'm not sure about the sequence. I worked furthest from the MC to closest, but that's not always the manufacturer's recommended sequence.

    no it always goes from closest to furthest, so you start at the driver side front and go around the car in a clockwise pattern.

    Always?! I see that's the correct (per service manual) for my RSX, but I've also seen a lot of "discussion" about this on clubrsx. Some saying there's no universal bleeding sequence, others saying just the opposite of what you said; that you should always do it the way I did it.......

    My head hurts....

    well when i took the ASE brake class that how they said to do it, but if you think about it logically you want to start with shortest and get all the old fluid out faster through the short line rather than rather then dragging old fluid through the longest line.

    I'm pretty sure I remember it's the other way around. RR > LR > RF > LF..

    Hmm.......seems to me, if you are only replacing fluid, and not bleeding a new or drained system, that it really doesn't matter. You should try and suck/push ALL of the existing fluid out, while topping off at MC to prevent air from entering. Removing all the fluid still entails sucking out everything that's in all the lines, short and long.

    But I think the real issue has to do with the brake circuit design, the MC, and the ABS unit, if so equipped. I think air can travel around from one line to another, or at least that's what I have been told.

    On my RSX, there are two lines leading into the ABS unit, and (of course) four leading out. Makes things a little more complicated, though I have no idea precisely what that means!
