A soft or spongy pedal is most likely the result of air in the brake system.  Air bubbles may have entered the system because the fluid level got too low.  The air could have been from a small leak in the brake hose(s) or a

The most common reason is over-torqued or unevenly torqued lug nut(s).  Making sure you use a proper torque wrench with all four wheels on the ground is the best approach.  The use of an impact wrench is NOT recommended.  Your vehicles manual will indicate the

Cracked discs or pad material build-up on the disc surface.  Excessive disc run out is another reason for oscillating feedback.

Brake squeal often happens during the first few hundred miles of use as pads bed in to a new or used discs.  It’s best to wait until you have about 1,000 miles (1,609km) before determining if there is a noise problem with your pads.  Some

Warped discs
Bad master cylinder
Caliper spread – which can lead to tapered brake pads
Calipers are not square to discs
Caliper piston(s) are not retracting properly causing one or more pads to constantly make contact with the disc surface.
Debris in the caliper

On your out lap (1st lap time on track) on the track perform a few near stops.  This will get the two surfaces (disc and pad) to mate up and put down a transfer layer into the micro-grooves on the discs.  Then, drive like normal

Brake discs do not require a detailed procedure as brake pads require.  By following the brake pad bed-in procedure will result in your discs being completely bedded.  If you purchase pre-bedded pads from G-Loc™ then all you need to do is install the pads and

If you have another manufacturers brake pad materials on your discs, then you definitely need to clean them up or get them turned by a professional before installing G-Loc™ brake pads.   To clean your discs, use a power sander with no less than 80 grit

Although a good idea, you don’t have to start with new brake pads and new discs.  If you want to keep your current discs, then you need to clean them up (see below).

Proper bedding of pads & discs will result in greater performance and longer pad life along with improved disc/disc wear.  Failure to properly bed in your pads will lead to increased wear of the pads.  It can also lead to glazing of both the pads
