Mazda CX-5 Mk1 2.2D SkyActiv — Sticking Brake Calipers (Slider Pins Seized)

Symptoms

  • Car pulls to one side when driving
  • Burning smell coming from one wheel after driving
  • One alloy wheel feels extremely hot to the touch
  • Severe, uneven brake pad wear

Root Cause

The rubber dust boots around the caliper slider pins perish or split. Water and road salt enter the cavity, rusting the steel pin into the aluminum caliper bracket.

How To Fix

  1. Remove the caliper and attempt to extract the seized pin using heat and vice grips.
  2. Clean the bore thoroughly with a wire brush.
  3. Fit new slider pins with high-temperature silicone grease.
  4. If the pin snaps, a new caliper carrier is required.
  5. Cost: £80-150

Other Faults on This Variant

Exhaust Camshaft Wear and Vacuum Pump Failure

Critical
2012-201440,000–90,000 miles£1500–£3000

Early SkyActiv-D 2.2 diesels have a soft exhaust camshaft that wears away prematurely. The metal shavings then destroy the vacuum pump and turbochargers.

Air Conditioning Condenser Leak (Stone Damage)

Minor
2012-201740,000–120,000 miles£250–£450

The air conditioning condenser is mounted at the very front of the cooling pack, making it highly susceptible to stone damage from the road, leading to refrigerant loss.

Front Anti-Roll Bar Drop Link Wear

Minor
2012-201730,000–80,000 miles£60–£120

The front anti-roll bar drop links wear out on heavily potholed UK roads, causing an annoying knocking sound at low speeds.
