does anyone know how to change the brake fluid on a BMW 730d please? Or any links for it?

Question

Any help greatly appreciated as have lost manual!

Answer 1

Changing of brake fluid is exactly the same in all BMW models.

On every brake caliper, there is a "bleed nipple", which; when loosened with a small wrench (8mm I believe), will start bleeding fluid. This is where you would connect the catch bottle.

1. Remove as much fluid from the brake fluid reservoir.
- Use a turkey baster

2. I recommend using a pressure bleeder with a bleed bottle
- Like this one from www.bavauto.com (Part # : PB03K)
- Next, fill up the bleeder bottle with new fluid, attach the bleeder's cap to the reservoir and start pumping according to the pump's instructions.

3. Changing brake fluid is pretty much an extended bleeding. So, work from: RR, LR, RF, LF.

4. You can see a color change between the old and new fluid while bleeding. As soon as the fluid changes colors, you can stop the bleed and work on the next wheel.

Answer 2

Go to your nearest motorfactors and get an EZI-BLEED, starting from the caliper the farthest away from the master cylinder,Gently crack off the blled nipple to make sure its free, connect the pipe of the bleed kit over the end of the bleed nipple,begin to gently pump brakes,once the fluid level in the resevoir drops to almost empty replace it with new fluid,once you have pumped all the fluid through to the back you will see the brake fluid go almost clear and air bubbles wil dissapear,once this happens,tighten up the bleed nipple then do the same always working from the farthest away,eg if the master cylinder is drivers side then start on the passenger rear then drivers rear then passenger front
