GW reader review opportunity: Textar conical adapters and DTI gauge

GW readers are being offered the opportunity to test and review Textar’s newly launched conical adapter ring set and DTI gauge, which are reported to help improve the accuracy of brake disc runout measurements.

What are these conical adapters for?

Textar say measurement errors often lead to brake juddering complaints by customers and even the most precise runout gauge cannot provide accurate values if the disc behaves differently during measurement and driving. 

This is because of how the brake disc fits on the hub. 

After all, the hub is only fixed in place by the mounted wheel.

For a runout measurement, the wheel must be dismantled.

If the wheel bolts are screwed in without the rim, they are almost always too long to provide a firm hold.

Textar say garages often use nuts as spacers but this solution has two disadvantages: firstly, most wheel bolts have a conical collar so a uniform holding force cannot be applied even when tightened crosswise and, secondly, the contact surface of the disc bell can be damaged when using steel nuts.

The first of these two disadvantages in particular can be enough to provide an unrealistic measurement result with low tolerances. 

Textar’s new conical adapter rings serve as both spacers and holders for the wheel bolt collar. 

Precise measurement

The stainless steel Textar adapter rings are available as a set of ten rings.

A complete axle can be measured using these rings and a precise runout gauge, such as Textar’s DTI gauge.

To prevent brake judder, every brake repair session should include a check of whether the runout of the brake disc is within the vehicle manufacturer’s tolerances.

Even small deviations, such as 0.05mm, can lead to vibrations that cause noise and/or brake judder.
