Vehicle Care 377
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climatescan cause a brake squeal when thebrakes are first applied or lightlyapplied. This does not meansomething is wrong with the brakes.
Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear andevenly tighten wheel nuts in theproper sequence to torquespecifications inCapacities andSpecifications0468.
Brake linings should always bereplaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedaldoes not return to normal height,or if there is a rapid increase inpedal travel. This could be a signthat brake service may be required.
Replacing Brake System Parts
Always replace brake system partswith new, approved replacementparts. If this is not done, the brakesmay not work properly. The brakingperformance expected can changein many other ways if the wrongreplacement brake parts areinstalled or parts are improperlyinstalled.
Brake Fluid
The brake master cylinder reservoiris filled with DOT 3 brake fluid. SeeEngine Compartment Overview0354for the location of thereservoir.
There are only two reasons why thebrake fluid level in the reservoir maygo down:
.Normal brake lining wear. Whennew linings are installed, thefluid level goes back up.
.Afluidleakinthebrakehydraulic system. Have thebrake hydraulic system fixed.With a leak, the brakes will notwork well.
Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it.
Do not top off the brake fluid.Adding fluid does not correct a leak.If fluid is added when the linings areworn, there will be too much fluidwhen new brake linings areinstalled. Add or remove fluid, asnecessary, only when work is doneon the brake hydraulic system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.

378 Vehicle Care
Warning (Continued)
Add brake fluid only when work is
done on the brake hydraulic
system.
When the brake fluid falls to a lowlevel, the brake warning light comeson. SeeBrake System WarningLight0140.
Brake fluid absorbs water over time.Replace brake fluid at the specifiedintervals to prevent increasedstopping distance. SeeMaintenanceSchedule0452.
Checking Brake Fluid
Check brake fluid by looking at thebrake fluid reservoir. SeeEngineCompartment Overview0354.
The fluid level should be aboveMIN. If it is not, have the brakehydraulic system checked to see ifthere is a leak.
After work is done on the brakehydraulic system, make sure thelevel is above MIN but not over theMAX mark.
What to Add
Use only GM approved DOT 3brake fluid from a clean, sealedcontainer. SeeRecommendedFluids and Lubricants0462.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.
Battery - North America
The original equipment battery ismaintenance free. Do not removethe cap and do not add fluid.
Refer to the replacement numbershown on the original battery labelwhen a new battery is needed. SeeEngine Compartment Overview0354for battery location.

How to Check Lubricant
2500HD with 6.0L
All Other Series and Engines
To g e t a n a c c u r a t e r e a d i n g , t h evehicle should be on a levelsurface.
.For all 4.3L and 5.3L 1500Series applications, the properlevel is 1.0 mm to 19.0 mm(0.04 in to 0.7 in) below thebottom of the fill hole, located onthe rear axle. Add only enoughfluid to reach the proper level.
.For 6.2L 1500 Seriesapplications, the proper level isfrom 15 mm to 40 mm (0.6 in to1.6 in) below the bottom of the
fill plug hole, located on the rearaxle. Add only enough fluid toreach the proper level.
.For all 6.0L 2500HD Seriesapplications, the proper level isfrom 0 mm to 13 mm (0 to 0.5 in)below the bottom of the fill plughole, located on the rear axle.Add only enough fluid to reachthe proper level.
.For all 6.6L Duramax Diesel2500HD Series applications andall 3500 Series applications, theproper level is from 17 mm to21 mm (0.6 in to 0.8 in) belowthe bottom of the fill plug hole,located on the rear axle. Addonly enough fluid to reach theproper level.
