Brake Squeal

new on here and just picked up an '05 Murano SL last night and have a front brake squeal when applying brakes lightly on pedal at speeds around 30 - 40 mph.

Took it back to dealer today, they tell me it is brake dust and they pulled it in shop and cleaned it. Service manager was the one even test driving it and said he heard nothing but had the brakes cleaned in shop anyways. Told me the brakes were even new and squeal is just dust or oxidation on rotors.

I drove away and still heard the same brake squeal.....wtf.

Are Murano brake pads horrible and cause brake squeal???.....if so, what is everyone replacing with aftermarket / non nissan brake pads?

Welcome to the forum.

The MO's OEM ceramic brakes are actually quite good. Great stopping power and very little visible dust.

It's possible whoever installed the new pads on your MO did not apply anti-squeal goo on the pads' backing plates, or possibly the shims were not replaced. That is easy to fix. Check out Eric L.'s excellent thread on the MO's brakes: Click Here

I've had terrible problems with Front Brake Squeal on my 07 SL.

For me it only happens in reverse and is so loud that it wakes my neighbors in the morning. It took several trips to the dealership including one with a video of the sqeal to prove my case.

The latest service note available to deal with the brake squeal problem is TSB NTB07-012A

2007 SL FWD

Why not just throw new pads on? Grease up the pad shims and caliper slide pins (with good quality brake and caliper grease), and you should be good to go.

You will save lots of time and $$ if you can do it yourself. The front pads on my 04 MO cost $25, and took about 1/2 hour to change.

Plus, you can put lifetime warrantied pads on and you'll never have to buy them again.

Any idea what models and/or years are covered by these TSB's?

IF YOU CONFIRM:

An applied vehicle has a "squeak" or "squeal" noise coming from the front brakes when:

^ braking in reverse while the brakes are cold.

ACTIONS:

On both front brakes, replace the brake pads with the parts listed in the PARTS INFORMATION section of this bulletin.

IMPORTANT :The purpose of ACTIONS (above) is to give you a quick idea of the work you will be performing. You MUST closely follow the entire Service Procedure as it contains information that is essential to successfully completing this repair.

PARTS INFORMATION


CLAIMS INFORMATION


Submit a Primary Failed Part (PP) line claim using the claims coding shown.

Note :The PBC Grease will service multiple vehicles, and is considered a shop supply - DO NOT submit this grease on your claim.

SERVICE PROCEDURE

1. Verify the incident by a test drive. Drive the vehicle as described in the IF YOU CONFIRM section in this bulletin.

2. On both front brakes, replace the brake pads with the parts listed in the PARTS INFORMATION section of this bulletin.

For more information on how to do this, see the BR section/FRONT DISC BRAKE/Removal and Installation of Brake Pad in the appropriate Electronic Service Manual (ESM).

NOTES :

^ Follow all CAUTIONS in the ESM procedure when removing and replacing brake pads.

^ Use an environmentally appropriate Nissan Brake Cleaner to remove the old PBC grease and/or brake dust from the "torque member". Consult local environmental regulations to decide which brake cleaner to use.

^ Apply PBC Grease (Nissan P/N 99990-00939P) between the brake pad and shim, and between the shim and piston to reduce potential noise. DO NOT GET ANY PBC GREASE ON THE BRAKE PAD 'FRICTION" SURFACES.

3. Repeat the test drive. Drive the vehicle as described in the IF YOU CONFIRM section on page 1 of this bulletin to verify the symptom is reduced.

This ones for front brake pulsation (judder) like when you hit the brakes at freeway speeds and the pedal/steering wheel shimmy.

NTB04-068

Date:
June 7, 2004
2003-2004 MURANO; BRAKE JUDDER FROM FRONT BRAKES

APPLIED VEHICLE:
2003 - 2004 Murano (Z50)

APPLIED VIN:
2003 Murano, all VIN's
2004 Murano, built before JN8AZ08T(*)4W 208518, or JN8AZ08W(*)4W 314242

APPLIED DATE:
Built before December 10, 2003

IF YOU CONFIRM:

While braking, especially during hard braking:
^ A steering wheel shake,
^ Body vibration, or
^ Brake pedal pulsation (also known as "brake judder").


ACTIONS:
^ "Turn" the front brake rotors using an On-Car Brake Lathe.
^ Install the new front brake pads and hardware kit (see Parts Information).
^ Burnish the brake pads.




SERVICE PROCEDURE

Turn the Front Brake Rotors

1. Remove both front brake caliper assemblies.
^ Refer to the Electronic Service Manual (ESM), section BR for brake caliper assembly removal.

2. Inspect the rotors to make sure they are serviceable (they can be reused/resurfacing is possible).
^ Refer to the ESM, section BR, for rotor inspection.


Minimum Thickness: 26.0 mm (1.024 in.)

IMPORTANT: If new rotors are required, "index" them to the hub (see "Rotor Indexing").

3. Resurface both front rotors using an On-Car Brake Lathe.

IMPORTANT NOTES: ^ You must use an on-car brake lathe (such as the ProCut(TM) PFM9.0 or equivalent). This is a required essential tool and must be used to perform warranty brake rotor surfacing.

^ The ProCut(TM) PFM9.0 can be ordered from TECH-MATE.
^ The on-car brake lathe is more effective in reducing brake rotor run out than the conventional off-car lathe method.
^ When using the on-car brake lathe, prevent metal shavings from contacting or collecting on the ABS speed sensors.
^ Remove any shavings that stick to the ABS speed sensor's magnet. It is best to clean the ABS sensor with the rotor removed.
^ If the rotor must be removed for any reason, mark the exact location (rotor to axle hub) before removing the rotor (see Figure

6). This will make sure you reinstall the rotor back to the same location.
^ Do not tighten the wheel lug nuts with an air impact driver.
^ Tighten the wheel lug nuts to the proper torque specification. Uneven or high torque applied to the lugs may distort the brake rotor and hub. This may result in increased rotor runout and excessive rotor thickness variation as the rotor wears.

4. After the rotors have been resurfaced:

^ Recheck the rotor thickness. Specification: 26.0 mm (1.024 in.) minimum thickness.
^ Check the rotor runout. Specification: 0.03 mm (0.001 in) maximum runout.

NOTE: Runout specification is new, and is slightly less than what is shown in the ESM.

5. Reinstall the brake caliper assemblies.
^ Refer to the ESM for brake caliper installation instructions.

Install New Front Pads and Hardware Kit


6. Replace the brake pads and hardware with the new ones listed in the Parts Information (see Figure 4).

^ Make sure the spring retainers and caliper slide pins are installed correctly (refer to the instructions supplied with the new brake pad kit).
^ Refer to the ESM for brake pad and hardware kit replacement instructions.
^ Use PBC grease on all shims as shown in Figure 4. Don't get grease on the brake pad surface.

7. Reinstall the wheels and lug nuts. Tighten lug nuts to 73 - 93 ft-lb with a Torque Wrench.

^ Do Not tighten the wheel lug nuts with an air impact wrench.
^ If you apply uneven or high torque to the lugs it may "distort" the brake rotor and hub. This may cause increased rotor runout and excessive rotor thickness variation as the rotor wears.

Burnish The Brake Pads

8. Burnish the brake pads as follow:
A. Drive the vehicle on a straight smooth road at about 30 mph (50 kph).
B. Use medium brake pedal/foot effort to bring the vehicle to a complete stop from about 30 mph (50 kph). Adjust pedal/foot pressure so that the vehicle stopping time is 3-5 seconds.
C. Cool the brake system by driving at about 30 mph (50 kph) for approximately one minute without stopping.
D. Repeat steps A, B and C 3 to 5 times to complete the burnishing process.

Rotor Indexing

When installing a new rotor, use the following "indexing" procedure. This helps ensure a minimum amount of rotor runout.

1. Make sure the rotor is fully contacting the hub. Clean the rotor to hub surface if it is rusty.

NOTE: For cleaning the hub surface, specifically around the wheel studs, it is recommended to use the Wheel Hub Cleaning Kit # J-42450-A, which can be ordered from TECH-MATE.

2. Install the rotor and all lug nuts. Tighten the lug nuts to 40 ft-lbs.

Place a reference mark on the rotor and hub (see Figure 6).


4. Measure rotor runout with a dial indicator (see Figure 7).
^ If the runout is above 0.03 mm (0.001), continue with step 5.

NOTE: This is a new runout specification. It is slightly less than what may be shown in the ESM.

5. Remove the lug nuts and shift the position of the rotor one lug then reinstall the lug nuts and torque to 40 ft-lbs.
^ Repeat step 4 until the rotor is positioned with the least amount of runout.

6. After you find the position with the least amount of runout, if the runout is still more than 0.03 mm (0.001 in), you'll need to turn (resurface) the new rotors. See step 3 in the Service Procedure.
