Ian Bright Motor Engineer

4.7/5

Ian Bright Motor Engineers is a friendly independent garage situated in a beautiful countryside location in Halnaker, Chichester. Established since 2013, our small team are dedicated to delivering you the highest levels of customer service. Our workshop is fully equipped and we cater for all makes and models of vehicles, offering our customers a comprehensive range of repairs, maintenance work, servicing and MOT’s. Owner Ian has over 47 years of experience, having started his 5 year City & Guilds apprenticeship back in the 70’s. City and Guilds qualifications are a lot more intense and labour intensive compared to the more modern qualifications available to mechanics nowadays, and we were taught how to fix and repair parts as opposed to simply replacing them, which is standard practice in most places today. I have experience working with older classic cars, alongside newer more modern ones too, and no job is too big or too small for us to take on! Most of my customers have been with me for years and know that by choosing my company to undertake works on their pride and joy, they will receive fantastic workmanship alongside a personalised service. We would never advise you doing anything to your vehicle which was unnecessary as some garages do purely for profit, priding ourselves on our honest core values. My son, who was trained in-house alongside me, has branched out into classic and vintage race cars and is fast gaining a fantastic reputation for his first-class trimming, and my eldest grandson Lewis is now working with me and is undergoing his apprenticeship too. Three more grandsons are also looking to come on board and keep this garage running with a strong family presence.

Frequently asked questions about a brake fluid change

Do I need to change the brake fluid?

Yes, you definitely need to change the brake fluid! Over time, it absorbs moisture, which lowers its boiling point and weakens its performance. This can cause your brakes to fade, work less effectively, or even fail.

What happens if I don’t change the brake fluid?

If you don’t change your brake fluid, you’re putting yourself in danger – it’s as simple as that. Over time, brake fluid absorbs moisture, lowering its boiling point which makes your brakes less effective. Old brake fluid can also cause corrosion in the brake system, leading to costly repairs.

Can I do a brake fluid flush myself?

You can, but it needs the right tools and know-how. It's usually safer and better to let a mechanic handle it to make sure it’s done right.

How often should I change the brake fluid?

Change your brake fluid every two to three years or every 30,000 miles. Check your car’s manual for exact timing.

Can I mix old and new brake fluid?

No, mixing is a bad idea. Old fluid may have moisture and dirt, which can weaken the new fluid. Always replace all the old fluid to keep your brakes working their best.

What is a brake fluid flush?

A brake fluid flush is when all the old fluid is drained out and replaced with new fluid. This removes moisture and dirt from the brake system, helping it work safely and efficiently.
