Properly torqued wheel nuts are  necessary  to help 
prevent brake  pulsation. When tires are  rotated, inspect 
brake  pads  for  wear and evenly tighten wheel nuts 
in 
the  proper  sequence to GM torque specifications. 
Your  rear  drum brakes  don’t have wear  indicators, but 
if 
you ever hear  a  rear  brake rubbing  noise, have the 
rear brake linings inspected immediately. 
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  brake pads replaced, have the 
rear brakes  inspected,  too. 
Brake linings should always be replaced as complete 
axle  sets. 
See 
Brake System  Inspection  on  page 6-15. 
Brake Pedal Travel 
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  apply the brakes,  with or without the 
vehicle  moving,  your  brakes adjust for  wear. 
Replacing Brake  System  Parts 
The braking system on  a  vehicle is complex.  Its many 
parts have  to be  of top  quality  and  work  well  together 
if 
the vehicle is to have  really good braking.  Your  vehicle 
was  designed and tested  with  top-quality 
GM brake  parts. 
When  you replace parts  of your  braking  system  -for 
example,  when  your brake  linings  wear  down  and you 
need new  ones put in 
- be sure  you  get  new  approved 
GM replacement parts. If you  don’t,  your  brakes  may  no 
longer  work properly.  For  example, 
if someone  puts  in 
brake linings that are  wrong  for  your  vehicle,  the  balance 
between  your front and  rear brakes  can  change  -for the 
worse.  The braking  performance  you’ve  come  to expect 
can change  in many  other  ways 
if someone  puts  in  the 
wrong  replacement  brake  parts.
