Hi
Just a quick question I changed the brakes on my M30 and had to remove the calipers.. this resulted in some brake fluid being lost. Can I just top it up or is it more serious?
Thanks
Mike

Re: Lost some brake fluid
It's your brakes man! Brakes are the one area on a car that I don't get to have a beer until after the job is done! 
Of course, that was back when beer wasn't being rationed like TP.
So you had to take the brake line off the caliper? Anytime you open that system up, air is going to get in there. Air compresses nicely and does bad things to the ability of your brakes to work as intended. There is also water in air, which I wouldn't want in my lines but I don't think the water is as big a deal as the loss of braking power that happens when that compressible bubble of air gets in the line.
So, with air in the lines, you can't stop in as short a distance - not a big deal until it is, and then it is a very big deal indeed.
Bleed those brakes.
On this topic, does anyone here have experience with the "Motive Products, European Power Brake Bleeder" on Amazon? I've been thinking about flushing the lines on my fleet and this makes it look very easy to pour through gallons of brake fluid all by myself.

The one that I bought is this: "PMD Products Pneumatic Brake Fluid Bleeder w/ 4 Master Cylinder Adapters 90-120 PSI". It requires an air compressor and works great for me.

Re: Lost some brake fluid
I have motive and it works great. You just have to make sure you bleed it in the order the FSM specifies and not far to near. Far to near doesn't work and it messes with your booster. Take it from someone who thought traditional bleeding was just as good.crrraaig wrote: ↑Tue Mar 24, 2020 7:36 amIt's your brakes man!
