EBC Brakes Premium OEM Replacement Front Rotors Audi A4 Quattro 1.8T 02-04
EBC Premium Disc - EBC is proud to be one of the only companies selling a British manufactured brake disc programme. Our high quality grey iron includes copper to increase thermal conductivity and wear properties. EBC Automotive brake rotors are made from G3000 spec cast iron and full specifications and properties can be seen here.
All EBC Premium Discs are cast to a material strength of 150N/m2 with a tightly controlled surface hardness variation less than 20 HB and are precision CNC machined to a surface tolerance of less than 0.05 mm. That is TWO THOUSANDTHS of and inch. For this reason EBC recommends a maximum runout of fitted rotors of 0.1mm or .004 inches (4 thousandths). TIR which means total indicator reading on a dial gauge.
Runout figures above this will lead to vibration after 3000 to 4000 miles due to what we call disc thickness variation (wearing a thin spot on the high point of the rotor as it runs off-true) which is NOT a warranty condition.
So you see this is no cheap import brake disc. These brake discs have the highest integrity and product quality on the aftermarket. An OE quality replacement disc, made of the finest grade steel and a perfect replacement disc for any car.
EBC also emphasises that disc must be fitted to absolutely clean hubs free of all dust dirt rust and scale and that COPPER OR MOLY GREASES are NOT used. Such greases contains abrasive particles which can cause runout being similar in effect to dirt particles on your hub.
When replacing rotors it is essential to replace the brake pads. At any brake service the brake pads are as important as the new brake rotor and not replacing with all new components could result in a safety issue.
If you wish to install brakes yourself and you are not a trained mechanic there can be safety issues. Replacing worn components can be achieved by competent mechanics but the brake hydraulics or the brake lines or brake caliper is quite a sophisticated part of your brake system and brake repair should be carried out by a trained proffessional
