Technical answers to the questions owners ask us — brakes, paint, fluids, chassis and diagnosis
Short, technical articles written from the workshop floor and the track. No brand or model sales talk: how things work, what fails, and what to check. Each article answers one common question.
- What is the difference between street, sport and track brake pads?Street, sport and track pads differ in friction level, operating temperature, wear, noise and dust. How to read the edge code and choose for your use.3 min read
- What are hot spots on brake discs, and why does my steering wheel shake when braking?Brake judder is rarely a warped disc. It is usually uneven pad deposits or hard spots in the iron. How they form, how to measure them and what can be fixed.2 min read
- Plain, slotted or drilled brake discs: which really brakes better?Myth vs reality on plain, slotted and cross-drilled discs: heat capacity, stress cracks, thermal fatigue, friction vs temperature, iron vs carbon-ceramic.3 min read
- Why does brake fluid need changing if it never runs out?Brake fluid absorbs water. DOT 3, 4, 5 and 5.1, dry and wet boiling points, hygroscopicity, and why heat makes it matter more.2 min read
- What is brake fade, and why does it happen on track?Pad fade, fluid fade, green fade and mechanical fade: what each feels like, why it happens on track and how to prevent it.2 min read
- What is PPF, and how does paint protection film actually work?PPF explained by layer: self-healing topcoat, TPU core, acrylic adhesive. Elasticity, elongation, tensile strength, clarity and haze — and what to ask for.3 min read
- Is ceramic coating worth it, and what does it really do?Ceramic coatings explained: wettability and contact angle, UV and chemical resistance, real thickness, what 9H means — and what a coating cannot do.2 min read
- PPF vs ceramic coating: what really protects the value of your car in Dubai?PPF absorbs impact; ceramic coating resists chemicals, UV and dirt. What each protects against in Dubai conditions, and why buyers check original paint.2 min read
- How often should a car be polished, and what does polishing actually remove?Polishing levels micro-roughness in the clear coat. Gloss, roughness, multi-step cutting, refining and finishing, pads and compounds — and why less is more.2 min read
- Can PPF be removed without damaging the paint?PPF removal risks: old film, aggressive adhesive, repainted panels, poor surface preparation. How removal is done and why zero risk can’t be promised.2 min read
- What can a paint-thickness gauge tell you about a used car?How paint-thickness gauges work on steel and aluminium, what readings mean, how to spot repaints and filler, and the limits of the method.2 min read
- What does a dirty throttle body do to an engine?Carbon on the throttle body restricts idle airflow: unstable idle, stalling, hesitation, fault codes. Why it happens and how it is cleaned and re-adapted.2 min read
- Is a thicker engine oil always better for protection?Viscosity, film thickness and friction losses from a fluid-dynamics view: what thicker oil does, why clearances matter, turbo vs non-turbo engines.3 min read
- Should you let a turbo engine idle before switching it off?Turbo cool-down explained: oil coking, water-cooled bearing housings, after-run pumps, and when idling before shutdown actually matters.2 min read
- Why do car batteries fail? Is it faster in Dubai?How lead-acid, EFB and AGM batteries age: grid corrosion, sulfation, water loss, parasitic drain. Why heat shortens battery life and how to test one.2 min read
- What do camber, toe and caster actually do?Wheel alignment explained for road and track: camber, toe and caster, tyre wear, turn-in, stability, and how springs and anti-roll bars change the balance.2 min read
- Air suspension or coilovers: which is better, and why does air suspension fail?How air suspension works and fails — air springs, compressor, valve block, dryer, sensors — compared with coilovers for road and track.2 min read
- Should I upgrade to polyurethane bushings?What suspension bushings do, rubber vs polyurethane vs spherical bearings: precision, compliance, noise, squeaks and where PU makes sense.2 min read
- Electric or hydraulic power steering: what is the difference, and which does my car have?Hydraulic, electro-hydraulic and electric power steering compared: feel, precision, maintenance, failure modes and repair cost implications.2 min read
- What tyre pressure should I run, and does nitrogen make a difference?Tyre pressure vs temperature, nitrogen vs air, mixing tyres, treadwear vs grip, wet vs dry grip, and how to read the DOT date for the UAE 5-year rule.2 min read
- What should I check before the RTA vehicle inspection?Pre-inspection checklist: tyre age and DOT code, tread, lights and bulbs, brakes, oil stains, windscreen, wipers, horn, warning lights and emissions.2 min read
- Why does my steering wheel vibrate, and what can I check myself?DIY checks for steering vibration: when it happens, tyre pressure, bulges, sand in rims, missing balance weights, wheel bolts and wear patterns.2 min read
- Where is that noise coming from? How to tell non-engine noises and vibrations apartA symptom map for chassis noises and vibrations: braking, above 100 km/h, over bumps, when steering, whistling, and drivetrain — with the neutral test.2 min read
- Why does my car’s AC blow warm at idle but cool when driving?Why AC cooling drops at idle: condenser airflow, fans, refrigerant charge, expansion valve, compressor control — and what is checked before replacing parts.2 min read
- What happens to a car after it has been underwater?Flood damage by system: engine hydrolock, contaminated fluids, electronics, chassis cavities and drains, interior foam and mould — and what to do first.2 min read
