Ford Fiesta Mk7 1.5 TDCi 75bhp — Sticking Brake Calipers (Slider Pins Seized)

The floating brake caliper design relies on sliding pins. In the UK climate, salt and water ingress cause these pins to rust and seize solid.

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

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

Other Faults on This Variant

DPF Blockage and Regeneration Failure

Moderate

2013-201730,000–80,000 miles£150–£1200

The 1.5 TDCi diesel Fiesta is commonly used for short urban trips — exactly the wrong usage for a DPF-equipped car. Blocked DPF is the number one complaint.

EGR Valve Failure and Intake Carbonisation

Moderate

2013-201740,000–90,000 miles£80–£350

EGR failure on the 1.5 TDCi Fiesta is a common companion to DPF issues. Carbon deposits block the valve and intake manifold, causing power loss and rough running.

Diesel Injector Failure and Rough Running

Severe

2013-201780,000–160,000 miles£200–£800

Common rail injectors on the 1.5 TDCi can fail, causing misfires, excessive smoke and hard starting. Injector failure can also result in diesel washing the cylinder walls, accelerating engine wear.
