Gud evening ZTH members, i had this problem with me for quite sometime now...i just did an engine conversion few months back(half-cut wit FR big disc and caliper) and after that my brakes is feeling spongy and hard at times....
i did brake bleeding a few times but the feel only last afew weeks and then brakes start to feel spongy again
regarding the brakes sometimes feeling hard, some said its the one-way valve, changed the whole booster and valve back to my original kancil one still the problem persist. But i guess it is caused by lack of vacuum cos when i pump on the accelerator pedal, the brake pedal will be soft again.
Because of this i'm scared to send my car for inspection until now. Is there anyone facing or have faced the same problem like this before? Has anyone tried modifying the brake system to a better one?
