The moment your driving down you favorite back road at a considerably fast speed and you go to press the brake pedal to realize you have no brakes. The corner I pressed the brakes on was a downhill right and I was going 70 around it. The car tripoded and the back slid. Lets just say a lot of poo came out.

When you want something with BMW part prices but with British reliability:

No brakes at all? OOOOF. Glad you are OK.

How? What happened?

Abs control unit went out and all of a sudden I had no brakes

Oh my gosh. I don’t even use brakes anymore

should downshift and slide the car into a corner like a pro.

I’m a novice here, but wouldn’t (/shouldn’t) that just leave you with functioning brakes without ABS ? I’m not doubting your experience obviously, so this seems like a design flaw or something?

Oh good! Another reason to trade my car in! I hope you know I already have, like, a dozen or so of these things.

I just checked and there was absolutely nothing in there in the brake fluid reservoir. Which is weird bc I filled it up a moth ago. Which means I have a leak in the brake lines

Considering I unplug my abs for every autocross I run and still have brakes I would say a line blew.

Have to have a leak in both braking circuits then.

That makes a lot more sense. I wonder if it was corrosion or some kind of obstacle puncturing a line.

Was there no light on the dash, warning you?

No light, which again is odd

When you say you filled it up a month ago, what prompted that? Did you do a brake fluid flush or something?

Not to tell you something you might already know, but the fluid level will drop as the pads wear, which is normal. Topping it off is ill advised because when you go to replace your pads and re-compress the caliper pistons the fluid will overflow the reservoir.

That said, if your fluid level got to the point where it was legitimately low but your pads and rotors were still in good shape it should have been a hint thay you should be concerned. It’s a closed system, after all, and the fluid doesn’t just evaporate. There should be evidence of a leak somewhere if you look in the right places (Residual fluid, etc) so best to start looking for the cause.

If you decide to diy, you may have issues getting the system refilled and completely purged of air without a computer to deal with the abs pump... And I can almost guarantee all but the most honest of shops will bend you over for parts you don’t really necessarily need if you bring it in. (IE: You just have a loose bleed screw, but that’s too cheap of a fix, so they claim you ran the master/slave cylinder/abs unit dry, it’s now seized and needs replacing at great expense to you)

Best wishes on getting it sorted, and staying safe.

Photo dump? Or did that already happen?

You shouldn’t be completely without brakes though as there are two circuits. Something odd going on, or not.

Is there a difference between British reliability and BMW reliability?

Don’t have the time for a photo dump sadly
