Mercedes GLA Brake Overhaul: All Four Corners Done Right

The GLA 200 came in for a routine inspection. The owner wanted everything checked before the next school run season. During our walk-round, we measured the brake pad thickness and found all four corners were running low. The front discs had scoring from the worn pads. The rears were not far behind.

This is the most common reason brakes fail an inspection in Singapore: routine wear, caught a bit later than ideal. Nothing dramatic, no brake fade or pulling, just discs and pads that had done their job and were ready to retire.

We put the GLA on the lift, removed each wheel, and measured the pad thickness on all four corners. Front and rear pads were both down to the last few millimetres of friction material. At that point little service life remains and replacement is due, front and rear.

The front discs had visible scoring, a groove worn into the friction surface by the pads running past the minimum. Scored discs bite unevenly and wear through new pads faster. Resurfacing (skimming) is not cost-effective for discs at this stage; new OEM items are the correct fix.

We replaced all four sets of discs and pads with OEM Mercedes-Benz parts in one visit.

• Lifted the car and removed all four wheels.
• Removed the worn pads and scored discs, front and rear.
• Fitted new OEM discs and pads to all four corners.
• Cleaned the calipers and greased the slider pins.
• Bedded in the new brakes before handover.
• Road tested to confirm even braking and no pull.

Using OEM parts on a Mercedes matters for braking balance. Aftermarket pads may cost less but the friction compound differs, which changes the pedal feel and can introduce noise. OEM discs are also matched to the caliper geometry from the factory. The car was confirmed clean before the owner drove it out.

A full brake overhaul covers all four corners in one visit with OEM parts, and we quote the exact figure before we start. It depends on whether the calipers need attention, whether you choose OEM or quality aftermarket parts, and the current condition of the wheel hubs.

Doing just the fronts costs less upfront but means a second visit for the rears when they wear through. With pads this close in wear level, doing all four at once is more cost-effective and keeps the braking balanced.

We quote before we start. If we open the car and find the calipers need work, we tell you before touching anything.
