so my ranger has abs so it wont have a proportioning valve. so what does it use when your towing. is it still 60/40 or does it go 50/50 with weight in the back. because i replaced my front pads twice and the shoes look perfect. i probably need to adjust them but im curious about the towing part. it doesnt have a level valve either. or am i not seeing it.
 
2001 and newer Rangers have an added feature called Electronic Brake Force Distribution. With EBFD, the 4WABS Module reads the ABS sensors and continuously computes the ratio of RPM between front and rear wheel pairs. If required during braking, EBFD modulates rear brake pressure to force the ratio toward one. So, it provides continuous, electronically controlled proportioning based on actual monitored slip rather than simply predicting slip using a preset mechanical prop valve. EBFD automatically adjusts on the fly for variables like weight distribution, deceleration rate and component wear.

EBFD is not the same as anti-lock which measures the acceleration of the tone ring at each sensor and cuts braking momentarily at impending lockup. This allow the tire(s) associated with that sensor to turn and (hopefully) regain traction. EBFD operates seamlessly during braking while anti-lock gives the familiar hammering sensation through the brake pedal.

This explains why I've only felt said "hammering" sensation while sliding through mud or snow and not during most panic stop scenarios under normal driving conditions. I just thought my abs system was flawed.

You the man, Bob!

Rwanzing, thanks for all the info o never knew any of this. I didn't think out has anything since out was a basic small sized truck. Do you think o need to adjust my drums our is it normal.
 
Might not hurt to check the adjusters, see if they run free and smooth.
Of course to do this you will need to disassemble the rear brakes on each wheel.

Another thought, when backing up, hit the brakes a little harder than normal, do this a few times. If the rear adjusters are working and that is an IF, then the brakes should adjust up.

Sometimes people while backing up either use their brakes with slight pressure or do not use then at all.
I have a habit of just slipping the trans in first and use the motor and trans to slow then move and there is wear and tear on the clutch, that’s another other story.
 
yeah i down shift all the time. but atleast i match the rpms, or try to atleast. but i should take them apart and clean them. maybe i can adjust them manually.
