Question about Isuzu Cars & Trucks
No country stated, no car stated.
no engine stated, petrol or diesel.
below is my wild and useless guess ,its petrol.
Power assist brakes work off a base of manual brakes.
my wild guess 2 is KB truck, in Africa
this next line means with booster off line
(hose plugged, and pulled)
do the base manual brakes work or not.??????????????
this is first. and a big safety issue.
is this hard to understand.?
is this your first brake job?
how the manuals work 101:
using up to 100 lbs of (man) force on the brake pedal; can get you 600 psi force at the rear of the mc, (and 4 time more at front calipers)
the pedal is 6:1 ratio, (approx)
the MC piston to the slaves (ratio) the front caliper pistons are huge (4:1), and 6x4=24:1 total . 24x100 is 2400 lbs, from you foot to pads.
the cars stops great like this.
assist only lighten the pedal load, needed.
allows 50 lb girl to drive car, or my pet chimp.
or old skinny grand ma , to church...
these facts are why the brakes still work in manual mode.
The stopping distance does not decrease with boost.
(granny excepted) one could call this granny assist.
see, in a shop full of men we can stop the car
fast and same low distance.
my guess is your post is about assist only.
not brakes dragging
not braKES WEAK.
assist is a whole other set of issues, if only assist fails....see?
