Many in the industry recognise the advantages of choosing remanufactured parts over costly equivalents, but as with new products not all remanufactuered products are of the same quality.
Brake Engineering has launched a campaign to highlight differences in various remanufactured products, warning the automotive aftermarket of the risks involved with choosing a remanufactured brake caliper that features several ‘reclaimed’ or ‘reused’ parts.
On the lookout
When remanufacturing calipers, only the core should be reused, having been subject to strict acceptance criteria and undergoing a stringent quality remanufacturing process that involves its inspection, dismantling, cleaning, rebuild and test. Brake Engineering calipers are also electroplated with a chrome 6 free finish to extend the life of the caliper.
Defining the industry standard
Once the core has been identified as suitable, the unit is ready to rebuild. It is at this stage where many braking remanufacturers cut corners, which can potentially be hazardous.
Let’s look at fixed and sliding calipers without the handbrake mechanism, and those with the handbrake mechanism.
In the units without the mechanism, used pistons will be corroded, pitted and the surface finish will have deteriorated to an extent that the piston pull back is compromised and therefore new ones are required.
As reclaimed seals will most likely be swollen and distorted due to fluid contaminants, new square cut seals should also be used.
Hard piston boots with an integral steel insert will be used and new soft piston boots will be fitted as the rubber perishes with age which makes them susceptible to accidental damage when fitting. Brake Engineering uses long-lasting boots made from the highest quality rubber that improves the reliability of the caliper. The importance of correctly fitted new piston boots is critical to the prevention of premature failure due to water or dirt ingress.
Brand new soft piston boot retaining rings, typically manufactured from spring steel without any sharp corners causing accidental damage by human error, should be added, as well as new caliper bolts. This is because ued bolts could have been over tightened and stretched beyond their design limits, which may lead to complete brake failure.
Brake Engineering’s range of fixed and sliding calipers with the handbrake mechanism incorporates many parts, from simple return springs to complex engineered components.
New pistons are required as handbrake pistons and their assemblies are highly stressed components that form an integral part of the self adjustment mechanism and functionality of the parking brake.
Potential damage to the circlip and spring cages may occur upon removal affecting the performance of the hand brake mechanism and therefore these too need to be replaced with new components, along with the internal seals as they can deterioriate within the brake fluid, causing potential brake failure.
Finally, new return springs should be used on the caliper as old ones suffer from corrosion and possible loss of temper.
Renew, don’t reclaim
When remanufacturing brake calipers, Brake Engineering adds an anti-corrosion coating, which is key to preventing rust, peeling, and corrosion.
Each Brake Engineering piston has an improved anti-corrosion coating and has undergone a 450-hour salt spray resistance test proving their suitability for use in cold climates, as well as having a hardness of 500vickers. The piston surface finish is improved too and therefore reduces wear on the seals.
Brake Engineering reconditions, re-engineers and remanufactures brake calipers to the highest possible quality before putting them into the range.
With a wide range of remanufacturing brands on offer, to ensure complete safety xit is imperative that the industry chooses the most reliable remanufacturing brand that has developed a reputation for using renewed parts. And with remanufactured parts already the cost-effective option on the market, there is no excuse for opting for cheaper calipers of poor quality.
