Solving Hard Brake Pedal Complaints On Subaru Vehicles

Some Subaru owners may experience a hard brake pedal (high effort) in extreme cold weather. Braking ability gets better as air temperature rises. The vacuum hose in these vehicles has an in-line check valve. Moisture can accumulate in the valve. In cold weather, the moisture freezes, blocking the vacuum to the booster, which causes the need for greater brake effort.

Low Speed Creak/Squeak From Rear Of Chevrolet Malibu

Some Chevrolet Malibu owners may comment on a squeak or creak-type noise coming from the rear of the vehicle. This noise occurs at slow speeds while driving over small bumps and is most apparent when the underbody of the vehicle is wet. This condition may be caused by the parking brake cables rubbing or slip-sticking on the retainer grommet.

Honda Tech Tip: Rattle From The Rear Shelf

Honda Accord owners may complain about a rattle that can be heard from the rear shelf area. Do not confuse this with worn upper strut mounts. The probable cause is the dynamic damper does not fit tightly against the rear shelf. To correct this, install washers between the dynamic damper and the rear shelf.

Toyota Tech Tip: Front Brake Rattle Noise

Some Corolla and Matrix owners may experience a front brake rattle type of noise when the car is traveling over bumps. Updated front disc brake cylinder (caliper) mountings and disc brake pad support plates are available to eliminate this condition. Conduct a road test to verify the noise condition. Front brake rattle noise will occur when the front tire runs over a depression in the road.

Measure Rotor Thickness, Runout: Stop Pulsation Comebacks Before They Start

Let’s say a vehicle had .003″ of lateral runout when measured at the outside face of the rotor. If this vehicle is riding on 205/55R16 tires, in one mile, the high-spot with .003″ of runout goes past the caliper approximately 836 times. Over 6,000 miles, that spot on the rotor will go past the pads more than 5 million times. Every time this spot passes the pads, a little bit of the rotor’s material is removed. Over the course of those 5 million revolutions, enough material is removed to create a thickness variation that can be felt by the driver. This is why it is critical to measure thickness and runout in a brake rotor and wheel flange even if new rotors are going to be installed.

How Ride Height Affects Toe Angle

How can a mysterious case of tire wear occur in a perfectly aligned vehicle? It happens and the answers aren’t always simple. To better explain, let’s go back a few decades when I aligned a 1983 Mitsubishi rear-wheel drive (RWD) pickup, only to have it return a month later with a tire scuffing complaint. My conclusion was that many independent front suspensions often require a “custom alignment” to compensate for variations in ride height caused by uneven loading.

Performing An Alignment On Ford F-150 And Lincoln Mark LT Vehicles

The 2004-’08 Ford F-150 and 2005-’08 Lincoln Mark LT are not difficult vehicles to align, but they are difficult vehicles to properly inspect and adjust to the optimal specifications. The main difference with the 11th generation is in the front control arms. The lower control arm is forged aluminum. Upper ball joints have a reputation for failing sooner than lower ball joints.

EPA To Propose Eliminating Use Of 134a In Vehicles, Consumer Products

According to the agency, a proposed rule will be issued this summer to withdraw approval for 134a for use in new motor vehicles and as an aerosol in consumer products. EPA pointed to the availability of substitutes for 134a in both motor vehicles and consumer products including 1234yf, which was approved under SNAP for use on vehicles.
