Unhappy That's not quite right as to bleeding brakes.

-When you get to the front calipers, there are 2 19mm bolts that hold the carrier and caliper to the strut, undo them and remove caliper, then swap out pads. Note those 19mm bolts should be in there pretty tight or even thread locked so have to give it some force to undo. The pads should just slide out, will be obvious when you have the carrier and caliper off.
(note when replacing pads, expecially with just cheap standard stuff it's best to do the disks at the same time, the disks should just be 2 torq screw holding them against the hub, t40 or t45 iirc although most cars don't have them due to being snapped off !)


To bleed the brakes you have to start at the furthest away from the master cylinder, so when looking at car, start with back left, then back right, then front left and finally front right.
-Bleeding is just a case of undo the bleed nipple on the caliper that you want to bleed and pump the brake pedal until a steady stream of fluid comes out. Note that you should only have 1 bleed nipple open at a time, don't bleed one caliper while having another calipers bleed nipple open.
To bleed brakes, it's best spray anti seize compound on the bleeder screws. Then see if you can loosen them. If everything is OK, you can start. Have someone in the car pump the brakes a few times and then stop, but keep applying pressure to the brake pedal and yell "I'm holding" At this point, the guy at the back left wheel opens the bleeder screw a half turn. The brake pedal will go to the floor (that's why the guy in the car had to keep pushing the pedal). Now the guy a the bleeder screw says "Hold the pedal down". He now tightens the bleeder screw. After the screw is tight (not super tight), the process is repeated until the brake fluid has no more bubbles in it. Oh, I forgot a step: get a piece of rubber or plastic tubing(clear if possible) that fits over the bleeder screw, and put the other end into a glass jar with about an inch of brake fluid in it. This way you can see the bubbles when you're bleeding the brakes. You should do it at least 3 times. Then do the next wheel. In the order mentioned above. If your car is older, might be a good idea to CHANGE the brake fluid. Remember to periodically check that your master cyl reservoir is not getting too low. If you break off a bleeder screw, you will have to drill the broken piece out and retap the hoe and put in a larger threaded bleeder screw or buy a new piston or have it renewed at a shop. Good luck
