Andrewwynn - which iso bubble tool did you use? Could you please provide a link?

There are quite a number of different tool options on Amazon. I found one with a review from "Andrew" but there was no associated video. Would be interested in what modification you made to the tool.

Thanks.

Andrewwynn - never mind, I found it from reading the other thread on the same topic.


For someone else reading this, the link is here.



Andrew, great job with the review. Thanks for taking the effort to do that - much appreciated!

Now I'm worried since my X5 been here in tri-state area all its life where it is exposed to road salt. Anyway, I will be inspecting it this weekend. Thanks for the heads up.



On a side note, I have had a brake line failure on a 2002 Ford F150 once. Good thing I was diverted on a local road due to traffic so only going very slow when lost the brakes. Anyway, repaired it with a new line then traded it in for another car. I will not keep a vehicle that is trying to kill me :-(

The link to the exact tool I bought:

http://a.co/5tXz9W0

The video is there showing the pitfalls and workaround to make it a five star tool.

Also read all the one star reviews. I posted a rebuttal to each one. They were all certainly operator error.



Pics or it didn't happen. The left is my first flare once I got the depth correct and the right was the factory flare.

I want to point out that since before 1963 (earliest car I've personally driven) there is no "going out"; the rear and from brakes are split apart and redundant. The brake pedal will tend to drop to the floor before the working pair of brakes are effective.

The failure in my case was a small enough that the brake pedal didn't drop fast it just kept sinking slowly.

You should be able to effect very strong braking with especially the back brakes out even though you will have to press the pedal much farther and likely much harder than usual. It's very good that the front and back brakes are separate systems.

That said they use the same fuid reservoir so I don't know how many applications you get before you have a problem. I refilled my brake reservoir as soon as the light came on and was able to drive nearly 3 hours and perhaps 7-10 applications of brakes. I also never held the brake pedal down at stops (used hand brake) and used engine braking to reduce the use of the brakes.

2-5 am and I wanted to get the truck home and on the parking pad where it will be repaired while the brakes still sorta worked.

Most of the cars I have seen have one front and the opposite rear on one circuit and the others on another circuit, i.e. front left and right rear on one circuit and right front and left rear on the other circuit.

The idea here is that if you loose a circuit (due to any hydraulic failure),
you will still have limited but even (directionally) braking.

This is also why you bled brakes in this pattern. Here in RHD-land we bleed brake in this order: -

Left Rear (longest line in the car), then
Right Front (shortest line but on the same circuit as the left rear), then
Right Rear (longest on the other circuit), then
Left front (because it's the last one!).

My ex 2002 Ford F150 had only three circuits; 2 going to front L/R and one going to the rear that splits into two; rear L/R. The rear brake line rusted out and leaked before the split and my brake pedal dropped to the floor. Had to turn back home and drive very slowly using only the emergency brakes (foot- activated one). I tried using the normal brakes again one more time and it went down to the floor so can't verify if ever will have brakes again after that leak.

Heads Up for Brake Line Check

In my 2-3 previous experiences of a blown brake line the pedal dropped to the floor however at that point it would still function I could stop the car fine on the remaining brake circuits.

With the abs able to stop the fluid to a particular wheel to assist in traction I'm a little surprised the system doesn't just shut off the circuit to a blown corner.

Would be nice to have this feature but how would the system "know" that a hydraulic failure had occurred downstream on the ABS modulator? Wheel speed sensors won't really pick up this and the ABS modulator probably isn't able to read fluid pressure.

I'm sure it could be done but the additional cost in the ABS system is likely prohibitive. Cheaper to regularly inspects the lines - like BMW suggest.
