Reply To: front brake master cylinder testing

[Laudanum]

stick a hose on it and clamp it to a set of bar in a vice, raise the open end of the hose so its above the level of the master cylinder, pump it slowly until all the air is out.
Now the fun part,pinch the banjo with your thumb and finger as hard as you can and slowly pump again, if its any good fluid should easily force its way out, don’t wear your best jeans, keep it away from your face and anything else you don’t want covered in brake fluid.
