Reno L4-2.0L (2006)
What is it and why
On vehicles equipped with pad wear indicators, an audible continuous warning can be heard when pads need replacing. This is not a malfunction.
It is an indicator that service is required.
What can be done
Have the brakes inspected by a qualified Suzuki service shop immediately.
With this in mind
Always have a complete brake inspection and diagnosis performed whenever a brake concern arises. These tips are to be used to help understand
normal brake conditions. It is not intended to provide diagnostics on any particular vehicle performance issue. Always take a brake noise concern
seriously and do a thorough inspection to eliminate any abnormal issues.
2.
Slight squeaking / squealing noise
Typical complaint
Driver complains that vehicle makes a squealing noise sometimes when applying brake pedal lightly at low to medium speed. The squealing stops
when applying the brake pedal with more force.
What is it and why
The brake system normally can make a squeaking and / or squealing noise whenever applying the brake pedal. These noises are caused by the high
frequency vibration of the brake pads against the rotating brake disc. Generally vibration can be an unavoidable result of friction generated by the
brake component. This noise can come and go depending on the weather conditions. This type of noise is normal and cannot be eliminated under
normal braking conditions.
What can be done
The level of vibration can be affected by ambient temperature and humidity, by road conditions such as dust, sand, mud and road salt. Also the
thickness or condition of the brake pad plays a role in many cases. Normally adding or removing shims and applying high temperature grease
between the pads and shims dampen and isolate most of the noise.
With this in mind
Have the brake system inspected and checked for pad thickness if the squealing noise is abnormally loud.
a.
Replace the brake pads if the thickness of the remaining friction material will not last until the next service.
b.
If the pad lining is thick enough to last until the next service; remove, clean, grease and reinstall the pad shims. Use high temperature grease.
3.
Groaning noise
2-1 Groaning noise on A/T model
Typical complaint
Vehicles with automatic transmissions may have a slight groaning noise when the driver brakes to a sudden stop and then allows the vehicle to
creep slowly from that stop.
What is it and why
This noise is caused by low-frequency vibration of the brake pads against the rotating brake disc.
This vibration transmits through the body components such as the suspension and the body panels.
Generally this vibration is an unavoidable result of the friction generated by the brake components.
The amount of vibration is influenced by the weather conditions. This type of noise is normal and cannot be eliminated under normal braking
conditions.
