Brake Wear 
Your vehicle has front disc brakes and rear drum brakes. 
Disc brake pads have  built-in wear indicators that make 
a high-pitched 
warning sound when the brake pads are  worn and new  pads  are needed.  The 
sound 
may come  and go or be  heard all the  time your vehicle  is moving 
(except  when  you 
are pushing on the brake  pedal firmly). 
NOTICE: 
Continuing to drive  with worn-out brake  pads  could  result in 
costly  brake  repair. 
Some  driving conditions or climates  may cause a brake squeal when the 
brakes  are  first  applied or lightly  applied.  This does not mean something is 
wrong  with your brakes. 
Rear drum brakes don’t  have  wear indicators,  but  if  you ever hear a rear 
brake rubbing noise, 
have the rear brake linings inspected. Also, the rear 
brake drums should be removed and inspected each time the tires  are 
removed  for rotation  or changing. When  you have the front brakes replaced, 
have the rear brakes inspected, too. 
Brake linings should always  be replaced as complete axle sets. 
Brake  Pedal  Trave/ 
See  your  dealer  if the brake pedal does  not return  to normal  height, or if 
there 
is a rapid increase in pedal  travel.  This could be a sign of brake 
trouble. 
Brake  Adjustment 
Every time  you make a brake stop, your  disc brakes adjust  for wear. 
Tf your brake pedal goes down  farther than normal, your rear drum brakes 
may  need  adjustment. Adjust them  by backing up and firmly applying  the 
brakes a few times.

Wheel  Replacement 
Replace any  wheel  that  is bent,  cracked  or badly rusted. If wheel  nuts keep 
coming loose, the  wheel,  wheel bolts, and wheel nuts should  be replaced. 
If 
the  wheel leaks  air, replace  it (except some aluminum  wheels, which can 
sometimes be repaired).  See your  GM dealer  if any 
of these conditions exist. 
Your  dealer  will know the  kind 
of wheel  you  need. 
Each  new wheel should have the same load carrying  capacity, diameter, 
width, offset, and be  mounted  the same way as the  one  it replaces. 
If you  need to replace  any of your wheels,  wheel bolts, or wheel  nuts, 
replace them only  with  new  GM original equipment parts. This  way,  you 
will  be  sure  to  have the right wheel, wheel bolts,  and  wheel nuts 
for your 
GM  model. 
NOTICE: 
The  wrong  wheel  can  also  cause  problems  with  bearing  life, 
brake  cooling,  speedometer/odometer  calibration,  headlight  aim,  bumper  height,  vehicle  ground  clearance,  and  tire  or  tire  chain\
 
clearance  to  the  body  and  chassis.
