A few possibilities exist: Your rear brakes may be binding (rusted pistons)
but usually that will affect one side more than the other. More common reason is that the master cylinder is bypassing or air has gotten into the rear half of the system. (usually the pedal won't feel "right" if either happens. If the pedal feels normal I'd look at the porportioning valve. If that fails, it will not permit pressure to reach the rear brakes.
As for the e-brake, they are really not designed to lock up but depend on vehicle weight and motion to cause them to hold. In the past they were used as a "fail safe" in the brake system. presently they are more used as a "hill hold" to keep pressure off the transmission and shift linkage when the vehicle is parked on a hill.
First make sure nothing in the brake assembly is binding and preventing full engagement, and that there is no air in the system or a master cyl problem, then check the valve.

Brake problem


try adjusting the rear brakes up correctly
the spring that holds the shoes together pushes all the brake fluid back into the reservoir and each application has to move the shoes back into contact with the drum
that is enough to get the pedal close to the floor

Right rear wheel will not turn 2004 xl7 susuki


This car ABS, if yes, try posting that, as i will answer for NO.
NO = short and easy. ABS = hard. (read the FSM , and see)
find a real shop with the ASE sigh,
never go there again. your dealer, he is bad for your health and others.
yes, my same bearing failed on my 04 but i found it with an electronic stethoscope (sonic ear) in 5min and did it early before brake damage.
locking brakes are very very bad , you need to find this fast.
he sounds incompetent.
if the Right rear is locked, the mech, loosens the bleed fitting
if it unlocks the MC is failing,(non ABS). mine is non ABS too.
if a new mc is installed and the rear piston clearance is not set
the MC will LOCK THE WHOLE SYSTEM up. or 1 end.
if the brake didnt release above, that means (gee simple) the brake neat
is locked. (bad bearing or wet soaked brakes or the parts assembled
ALL WRONG here.
puddle on floor, is it DOT3/4 fluid or GL4 gear lube.
surly you can tell the diffr, between them.> no?
if fuild that is wheel cylinder failure.
did you use non DOT/3/4 fluid, you must not use dot 5 or the seals will fail FAST,.....
using jiffyboobs? dont/

abs stops the wheels from locking up in an emergency brake situation,you will feel the grab-release,grab-release on the brake pedal......

Brake peddle is hard and bled all four wheels and no fluid comes from the back wheels


If you have ABS fitted - it could be that it has detected a leak (yes - you bled them) - but in this case it has sealed off the (defective) rear wheels, and is just giving pressure to the front.

If you turn your ignition on - and it comes up ABS light, then I'm afraid you need a scanner to reset the ABS system as it has now probably locked up in this position.

Just another way for dealers to grab your wallet. Sorry.
