Anybody had problem with ABS pump?
« on: April 29, 2021, 04:58:34 PM »

V7II 2016 ABS STONE owner

I recently had an issue with my front brake sudden sponginess (not after month sitting in a storage but during regular use)
and my dealership suggested me to replace the master cylinder. long story short I ordered and replaced my self the MC but I still have an issue of sponginess.

So I tried connecting a new steel line directly from MC to Caliper and the lever is rock solid.
if I bypass the ABS it seems to work well, but very spongy if i connected back to the oem lines going thru the abs

now, either the problem are the lines, which are only 3 yrs old
or the abs unit is sucking air somewhere?

did anyone experienced a similar problem?
