- Fully floating 2-piece rotor that allows outer ring to expand freely in response to heat. This reduces stress which in turn extends rotor life and reduces the tendency for rotor cracking during extreme use.
- Drive bobbins machined from a single piece of stainless steel giving maximum strength and corrosion resistance. Stainless bobbins reduce the requirement for regular disc maintenance and ensures the outer ring continues to float freely even when used on the public road with corrosive salts and other road grime.
- Each bobbin assembly features an anti-rattle spring clip ensuring silent operation when driving on the public highway
- Rotor rings feature 48 directional internal curved vanes for improved rotor coolin
- Friction rings are cast from high carbon G3500 alloy giving excellent wear properties and improved thermal capacity. All EBC disc rings are cast using the ‘centre split’ casting method, ensuring a balanced casting that will not distort under high heat, an issue common with cheaper ‘moulded out’ castings.
- Unique Swept Groove slot design for effective evacuation of braking dust and gasses whilst ensuring good initial ‘bite’ on brake apply
- Replacement disc rings for EBC floating rotors are significantly less expensive than our major competitors.
EBC Automotive Brake Tech – brake calipers
Brake calipers are a vital part of your brake system. The brake caliper is what brings the disc brake pad into contact against your brake rotor and generates the stopping power of the vehicle. Seized calipers or seized sliding parts of the brake caliper will cause many problems including brake drag, brake overheat and hot spots on brake rotors, cracks in brake rotors and very commonly rotor ribbing or rotor galling which shows up as record style grooves or ribs on the rotor in a general pattern.
Whilst it is not within the ability of most mechanics to strip and refurbish a brake caliper, certain service work can be carried on by competent technicians or by your dealer. Do NOT please attempt to rebuild brake calipers as this is a SAFETY ISSUE if you are not totally qualified to do this. Our following notes guide people in the basics of making sure your caliper is working properly.
There are several types of automotive brake caliper.
Most cars use a single piston sliding caliper which has a single large piston, on the inboard side of the caliper into which the hydraulic fluid enters. Through a slider mechanism the opposing half of the caliper is pulled towards the piston clamping the brake pads on to the brake rotor. These sliding calipers as they are know are prone to seizure due to corrosion in two areas.
It is essential that these slider pins and the holes into which they fit are free of all dirt rust and scale and are fully lubricated with a high temperature lithium soap base grease and that the bellows seals which enclose these pins fit snugly and are not split or perished whereby they might allow moisture into the slider bores.
Shown below are the slider pins that are part of the carrier and fit inside blind holes in the caliper body
If your brake rotor looks like this in the picture below, it has to be turned or replaced and new pads fitted. The matching faces on the brake pad will show rib marks.It is most common in European cars that these slide rails become rusty and the free movement of pads cannot take place. On every brake pad change, clean these slide rails with a wire brush and apply a VERY THIN coating amount of high temperature grease on them, take care not to contact the brake pads with ANY greases or lubricant which can ruin the brake pads and can CAUSE TOTAL LOSS OF BRAKE in driving.
Again EBC Brakes wants to draw customer’s attention to the numerous advantages of slotted rotors or drilled and slotted rotors such as our GD series or USR series sport rotors which eliminate rotor ribbing, eliminate rotor scoring and rotor damage, help brake pads last longer and run cooler.
