Brembo Monoblock ,check Banjo

Well after stuffing around with Radial brakes and new lines ,I still was not happy with the feel ,Well i have no idea why Brembo would only drill a .05 mm hole in the brembo disc brake banjo bolt , I drilled it out to 1.5mm on both brembo disc brakes and had an amazing difference in grab .Anyone know why Brembo would make a banjo bolt with such a small outlet flow ,most banjo bolts on many other bikes are around 1.5mm hole to 2mm hole .So before you change master cylinder ,brake pads ,lines and all the other parts ,change the Banjo bolts first . Only the bolts guys .Might just get rid of that wood feeling.

cheers eddy

That's an interesting observation and fix. Without checking others, might it have been a manufacturing defect?

On a single bolt, maybe...but if every bolt on the bike was that way, no.

I used to be fast....now I just dream about it.

Its extremely small ,and at first i could not see the hole and used my glasses to see it ,now that's small ,and wonder if this is the go with other models ,No idea why ,I am no engineer ,but the smaller the hole the less fluid passes ,I think and less pressure ?

Pressure transmits evenly and undiminished throughout a fluid to the walls of its container.

However, as the fluid goes through a small opening, there is a significant pressure drop.

it eventually equalizes if allow to stabilize.

The process is slowed through the small opening.

with a hole that small it seems the size of the master cylinder plunger would not make a difference in stopping power
