Most modern vehicles have calipers on the front wheels, while many also use them on the rear. Because calipers live right next to the wheels, they absorb incredible amounts of heat and are constantly exposed to road grime, dust, and moisture. Over time, the internal rubber seals can perish or the metal components can seize, leading to dangerous "brake drag" or a total loss of stopping power.

What common symptoms indicate you may need to replace the Brake Caliper?

Car Pulling to One Side: If a caliper is seized "on," the car will pull toward that side while driving. If it is seized "off," the car will pull to the opposite side when you actually hit the brakes.

Soft or Spongy Pedal: If a caliper is leaking fluid or air has entered the system, the pedal may feel "mushy" or sink all the way to the floor.

Abnormal Squealing or Grinding: A stuck caliper can cause the pads to rub constantly against the rotor, creating excessive noise and heat.

Visible Fluid Leaks: Finding an oily, clear-to-amber fluid on your inner wheel rim or on the driveway is a major red flag for a caliper seal failure.

Reduced Braking Power: You might notice it takes significantly more effort and distance to bring the vehicle to a complete stop.

Common causes

Heat Degradation

The extreme heat generated during braking eventually hardens the internal rubber seals, causing them to crack and leak.

Contaminated Brake Fluid

Brake fluid is hygroscopic (it absorbs water). Old fluid leads to internal rust and corrosion, which can cause the caliper piston to seize in place.

Worn Pads and Rotors

If you drive with paper-thin pads, the caliper piston has to extend further than intended. This can cause it to become stuck or tilt, damaging the bore.

Road Grit and Debris

Dust from South African roads can get trapped under the caliper's rubber boots, tearing them and allowing grit to score the metal piston.

How it's done

Inspection: The professional identifies the faulty caliper and checks the condition of the brake hoses and rotors.

Removal: The wheel is removed, the brake line is plugged to prevent fluid loss, and the old caliper and worn pads are unbolted.

Replacement: A new or refurbished caliper is installed. Because a faulty caliper often ruins the pads through uneven wear, new brake pads are typically installed at the same time.

Fluid Flush & Bleed: Fresh brake fluid is added, and the entire system is "bled" to ensure there are no air bubbles in the lines, which is critical for a firm pedal.

Torquing: The wheels are reinstalled and tightened to factory specifications using a torque wrench.

Performance Test: The professional performs a road test to ensure the car stops straight and the pedal feels firm and responsive.

What to expect

This service generally takes between 1 to 2 hours per axle. You can choose to have a mobile service come to your home or office, or visit a vetted partner workshop for the repair. You should notice a significant improvement in steering stability and braking confidence immediately. There may be a short "bed-in" period of a few kilometers where the new pads settle into the rotors.

Keep in mind:

Replace in Pairs? While you can replace just one caliper, it is often recommended to at least service the other side to ensure balanced braking force across the axle.

New Pads are Non-Negotiable: Never install a new caliper with old, unevenly worn pads. It will prevent the system from working correctly and can damage the new part.

Check the Hoses: Brake hoses can deteriorate internally. If you’re replacing a caliper, ask the professional to check the hoses for blockages or bulging.

Don't Ignore Leaks: Unlike engine oil, you can never "just top up" a brake fluid leak. Any loss of fluid means the system is compromised and needs immediate repair.

Our recommendation:

Keep up with the regular brake services as suggested by the manufacturer.

If you drive the car with thin brake pads or rotors, it will ruin the callipers.

Change the brake fluid regularly (approx. every 45 000 kilometres).

If you notice a clear fluid on the tires or on your driveway and a change in the way the brake pedals feel (softer pedals), it is time to get the brake system inspected.
