I have a 2004 525i with automatic transmission & M54 engine, recently I have been having trouble with my brakes making a squealing sound from the front passenger side wheel while they are spinning between 30-45mph, I plan on changing out the clips, bushings, & while apart if the pads need to be changed I also have a new set to put on as well. my question is regarding my brake fluid however, I don't have a vacuum or pressure bleeder of any kind the only thing I have similar would be a fluid transfer pump, im wondering if it would be ok to use the pump to suck out the fluid in the reservoir, then replace what was removed with new fluid or if this would be harmful to the car somehow due to the old/new fluid mixing?

It will be ok to do or you can do a self bleed if you have no one to assist you. You do not need any sexual tool for bleeding. Having one does make it easier if you know how to use it correctly but not necessary.

well I hope u don't need a sexual tool for bleeding hahaha but no that's my issue is Ihave no pressure bleeder nor anyone to help me an I haven't been able to find anything for sure about how to bleed correctly with only one person.

If you use the self bleeding method or gravity bleeding method you can accomplish it by yourself. Just be sure to put fresh fluid in the reservoir before starting. It's time consuming but no need for another person

do u have a link to info on the self bleeding/gravity method? I plan on doing it today since I'm going to be changing the bushing as well as the anti rattle clips on the front wheels

BavAuto, and presumably others, sell a kit wherein you pressurize the resevoir while you open and close each fluid valve at the caliper. This is the only way that I know of to do it by yourself.
