First Line is using its renowned Borg & Beck brand to promote the importance of best practice during brake installation.
By following the correct procedures, it says possible complaints will be significantly reduced, saving time and inconvenience for both technicians and their customers.
There are three main habits that some still adopt during installation, that if not corrected, can cause potential issues.
Firstly, the use of copper grease on the back of brake pads is a definite ‘NO’.
A First Line spokesperson said: “This can lead to complaints of noise and possibly affect the free movement of the pads.
“This is because Borg & Beck brake pads have double rubber shims on the back to absorb any noise and vibration, therefore there is no need to apply anything else to the back of the pads, as this will be detrimental to their functioning.”
It is also vital that the mounting surface of the disc and the vehicle’s hub are totally clean and free of rust and debris.
“The hub should be cleaned using a soft wire brush or emery paper, then wiped with a cloth and solvent,” the spokesperson explained.
“A small amount of debris not cleaned away can cause an instant problem of excessive run out, which will be felt through the steering wheel.
“Best practice to check if the discs are parallel to the hub, is to check the run out of the discs.
“This should not exceed 0.08mm, if the run out exceeds this, the disc must be removed and the hub cleaned again.
“If this has no effect, the hub should be measured for run out as well.
“Hub run out in excess of 0.04mm is likely to cause a problem and should be investigated.”
When new pads and discs are installed together, workshops are encouraged to remind customers that they must be bedded-in properly.
Failure to drive sensibly for the first 400 miles could lead to a hot-spotting incidence, which if severe will induce disc thickness variation (DTV), a problem that develops over a few thousand miles before being felt.
First Line has made its advice available in the form of workshop posters.

In addition, a rear-view mirror hanger has been designed and is being put in the box with the brake discs, so that they can be placed in the vehicle after installation to encourage the driver to “take it easy”.
