Am i missing something? Is bleeding the brake system part of a standard brake job? It was not suggested in the DIY. Is this what BMW mechanics do? It's worth a try I guess. I am a little confused here... please explain. Does compressing the piston with the c-clamp introduce air bubbles? How did I get air bubbles!!!! Is this why the DIY suggested optiional step of opening the Master Cylinder Brake Resovier cap?!!!

Step 1:Loosen the Master Cylinder Brake Resoivor Cap*** I find his step is optional and do not do this myself ***Proper procedure does call for loosing this cap when you compress the calipers back as fluid is pushed back inot the master cylinder. I've done this hundreds of times without loosening the cap with no ill-effects. You can do either. When in doubt, play it safe.
Open the hood and loosen the Master Cylinder Brake Resevoir Cap. Do not remove it, just loosen it all the way.
The Master Cylinder Brake Resovier cap is located on the driver side at the back of the engine on the firewall. Its a semi-transparent canister showing the level of brake fluid in it.

I am just a little hesitant because I am reading horror stories about brake bleeding on the X5. Also I read somewhere that you need some sort of computer to do this to cycle the ABS unit but maybe that was just if you get air in the abs valve. I guess for normal bleeding air cannot enter the nipple on the caliper and you never let the fluid level go below the minimum level so any air bubbles are just pushed out?
Any tips or links to procedures for this? I really don't want to f it up worse
Is this something I should not attempt myself and just take it to an indy mechanic?
Someone please set the record straight on bleeding and if it is needed in my situation...
