    I bought a new ToolPro 18 PCE disc brake pad and caliper service tool kit to push the piston in when changing brake pads along with a Toledo brake bleeder & fluid extractor 1L to bleed the lines but im not sure if I have to pump the brake pedal after the new pads are in and to do this before I bleed the lines, ie:

    1. remove brake fluid cap in engine bay
    2. take caliper off and remove old pads
    3. use ToolPro service tool kit to push the piston in
    4. put new pads in and replace caliper
    5. do as above for other 3 wheels
    6. pump brake pedal about 6 times to push pistons back out
    7. bleed brake lines using Toledo extractor in correct order

    Is the above correct? I'm doing this on my own hence the Toledo extractor with an air compressor.

    All you're doing when you pump the pedal is resettling the pads in the calipers. Dont need to, but wont hurt if you do either.

    Also, you'll want to suck a little bit of brake fluid out of the reservoir before you push the pads back.

    They say for ABS you should open the bleeder nipple before pushing the pistons back to avoid damage, don't no if its true or not just seen it on a U-Tube video, I've never have and hasn't hurt my vehicle.
    Remember you always start from the back left then back right front left then front right.
    Make sure there no bubbles in the tube then tighten.

    i sucked as much out of the m/c, refill with new fluid and flush with the piston pushed in to get as much old fluid out of the caliper
    you can crack the bleed nipple as you are pushing the piston in so the old fluid dosen t mix with the new

    left rear is the longest just and keep your eye on the reservoir keep topping it up
    i have a air bleeder and it came with a bottle you fill and put in the reservoir
    best 20 odd bucks from ebay just makes brake flushing a breeze

    Thanks everyone, one last question starting from the rear left is it ok to suck as much brake fluid out of the reservoir in the engine bay then push the piston in and then once the caliper is back in the car with new brake pads suck whatever is back in the reservoir out and repeat for the other 3 wheels and then fill the reservoir to start the bleeding process or does doing it this way cause too much air to get in the lines?

    WTF.

    Step 1. suck out old fluid in the reserve and wipe out clean.

    Step 2. Fill reserve with correct fluid with a different color if u can.

    step 3. With wheels off crack bleeder with hose attached.

    Step 4. remove and replace pads.

    Step 5. Starting from back left start your flush until your new fluid shows up and looks clean with no air bubbles, do nipple up. (Note don't let your reserve run out.)

    Step 6. Repeat process with other 3 lines keeping a eye on fluid level in your reserve.

    Put a long straw down the tranny dipstick tube and suck it out.

    Not when they just want new pads all around.

    By sticking the tube down the dipstick, yes it works as I used it on mine before removing the pan.

    Saves cleaning up your driveway after you spilt tranny fluid all over the place trying to remove the last bolt while holding up the pan, unless you have a car hoist good luck to you.

    Righto smartarse, every one's got one of those haven't they as they work on transmissions everyday.

    There are ways to do it without any specialist tools and not make a mess, obviously you're not that clever.

    I use a 2ft by 4ft drain tray - It holds 12lt.
    Of course now I have a drain plug in my trans pan, so not as necessary anymore.

    I didn't say they did I just quoted the guy who has one and said its also good for removing fluid from the trannie, meaning it can be used for more than just as a brake bleeder.

    Yes I know I am cleaver, you can leave 2 bolts on one side in each corner so you can tilt the pan down.

    Yes you can but if your on your back under the car the tray gets in the way.
