Fibrax Disc Brake Cleaner



Formulated to be safe for your bike while cleaning things up a treat – and it's made locally

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Fibrax Disc Brake Cleaner is formulated to be safe on your bike, and does the business removing residues that will affect your brake setup. And if shopping local matters to you, the component formula and parts are all made within 40 miles of Fibrax's canning plant in Cheshire, close to its North Wales HQ.

Chances are you've ridden a bike with Fibrax products on board – brake blocks, disc pads, cables or other small bits and pieces. It has its own laboratory and material scientists, putting its various products through stringent tests to ensure they meet the appropriate standards.

Fibrax measures the braking force applied at the lever versus the resultant force slowing the wheel on a rolling road. As Fibrax has the ability to do bike-brake-specific testing, it can say that brakes cleaned up with Fibrax Disc Brake Cleaner deliver an 18% improvement in braking force compared to a 'contaminated' system. There were Newtons, Meters, miles-per-hour and other such boffinry involved in the discussion I had with its cycle sales manager Ellis Blackman, but the end result is that apart from not only making things look shiny, removing contamination actually makes you faster – because as any fule kno, to go fast you need to be happy you can stop fast too.

The Fibrax formula is designed not to degrade the material in the brake pad – apparently many disc brake 'cleaners' do degrade pad material by softening the top layer, which means pads wear faster. A bonus of not dissolving pad material is that the cleaner doesn't break down the embedded or 'burnt in' brake pad material on your rotor. This is an important point, as you need pad material on the rotor to give the pad itself something to grip. If you've ever ridden a brand-new disc brake rotor (or one that's had the rotor sanded back) you'll know how much better they are after they've been 'burnt in' by repeated hard decelerations to get the rotors piping hot and material evenly transferred.

Because the formula is safe on frames, tyres and paintwork, Fibrax recommends cleaning the brakes on the bike. First give the brake a blast, wait 10 seconds, then give it a second blast to wash off the crud that's just been loosened – similar to foaming bike cleaners.

Fibrax suggests you could clean the brakes after every ride, as the formula is safe and therefore application is easy.

> How to fit disc brake pads

Over a good few wintry months and through a full can of the stuff, I'm happy to report that it just works. The pressure is good from the nozzle, so while things won't look spotless on a mucky calliper, all the big, built-up stuff gets blown away. I noticed in very cold weather, if you applied the brakes immediately after a cleanup there was some squealing that did go away after a few hard stops. Experimenting with a brief blast from a hose to completely wash away all traces worked well, delivering squeal-free braking from go.

Out on the road, braking remained consistent, with noticeable improvements going from a filthy setup to one blasted clean. My fingers aren't calibrated to the extent that I'd swear it was 18% better, but things were clean, worked and I wasn't fearful my bike was being eaten by nasties.

At £6 for 400ml, the cleaner is priced about midrange. For that, you're getting made-in-the-UK properly-boffin-based cleaning that does the job and is friendly on your bike. Recommended.
