Brakes

Why are my brakes soft when I step on them?

Vehicle has sat idle for 3 months - no problem before sitting idle.

Because you most likely have not taken the brakes apart on a yearly
basis,to remove all rust & after cleaning & inspection of all brake components
& decide if any need to be replaced or machined,then followed by actually
using the proper lubricants were required,something seldom done or done
properly

You need to flush brake fluid every 2 years or the inside of the system turns to
rust from moisture & many components are ruined & you have problems

A soft pedal is air in the system,so that had to be there in some amount for
a long time

Just having a vehicle sit,if outside, requires the above procedure to be done yet
again,all you will have is a rusty mess & brakes that don't work well & a not safe
to use

Saying you had no problem is only your perception of a symptom,not the actual
mechanical & hydraulic condition that may be there now
