Looking for a station wagon to park in your driveway with 450 horsepower under the hood? Well, the new Audi RS 4 Avant may be just what your driveway needs. Audi has taken their third generation Avant and added a bunch of high performance goodies to make that weekly run to the supermarket just a little more fun.
The Audi RS 4 Avant uses the same high-revving, normally aspirated V8 engine that powers the RS 5 Coupe. The 4,163 cc powerplant produces 331 kW (450 hp) at 8,250 rpm for a specific output of 108.1 hp per liter. Its maximum torque of 430 Nm (317.15 lb-ft) is available from 4,000 to 6,000 rpm. All this means the RS 4 Avant accelerates from zero to 100 km/h (62.14 mph) in 4.7 seconds on its way to a governed top speed of 250 km/h (155.34 mph). This can be increased to 280 km/h (173.98 mph) upon request.
Audi has revealed the new 2012 RS4 Avant. Audi RS4 Avant is powered by a 450 bhp 4.2 liter V8 engine which delivers power to all four wheels via a seven speed dual clutch gearbox. The RS4 Avant can speed from 0 to 60 mph in just 4.7 seconds and reach a electronically limited top speed of 250 kmph, which if removed, can allow the RS4 to speed to a top speed of 279 kmph. The powerful engine delivers a mileage of a little over 9 kmpl.
2012 Audi RS4 Avant's 4.2L FSI engine is hand built at Audi Plant in Gyor, Hungary. High level of efficiency, coupled with a host of internal and external upgrades is what will set this 2012 Audi RS4 Avant apart from competition. External features would include 19 inch ten spoke aluminum wheel shods and 265/35 series tyres. All aluminum suspension ensures that the vehicle has lower road clearance of about 20 mm less than what is seen on the previous A4 Avant. Prices will start from €76,000 and bookings are expected to commence in Summer this year.

How to remove and replace the front brake rotor wheel bearings on a 92 Buick Roadmaster?
Jul 14, 2009 by genlee69rt01 | Posted in Maintenance & Repairs
I have done a ton of brakes but this is the first time I have run into the bearing in the rotor. I usually work on newer cars too...
But do you replace these or can you re-use them on the new rotors? Do you need a special tool to remove/replace them?
Any help on this would be great! Thanks!
First things first SlopeDir, hello? "Roadmaster" which refers to the rear wheel drive dinosaur!
Now. Too your question: No you do not need any special tools.
First remove wheel, Second remove caliper, next remove the rotor, now we remove the bearings.
To remove the races, all you do is put back the large nut that holds
the rotor assy. to the hub, now put the rotor assy. back on the spindle,
over the nut. You will need to let the rotor assy. rest down onto the spindle, then give a hard pull(sometimes takes a couple of pull), but the race (inner race) will pop out.
Use a pry-bar or screw driver to knock out the small outer race.
You will need the old races to properly install the new races. Tap them down with a hammer.
Reinstall Bear-rings(grease first) and re-install rotor assy. to the hub.
reinstall caliper and tire.
Do one side at a time just in case you need a guide.
Good luck

Is this FWD? Newer GM FWD use integrated hubs with bearings and speed sensors, all one part and no adjustments. Or is your car one of those old RWD dinosaurs?
SlopeDirk | Jul 14, 2009
you will need a race driver to set the race for the new bearings, dust shield, grease, cotter pins that should do it
mike d | Jul 14, 2009
It is always a good idea to replace them. But if money is tight you can reuse them. Just make sure their still tight and repack them with grease good. Most new rotors come with races, so you won't have to worry about getting them out, just use the bearings and the seal. When removing the inner bearing use a brass punch to knock it out. Other than a brass punch, no special tools required. Hope this helps.

why does the front brake rotor get hot after driving? Is it normal?
Mar 20, 2010 by kyfat | Posted in Maintenance & Repairs
why does the front brake rotor get hot after driving? Is it normal? and to what degree can it stand before it becomes a problem?.
Disc brake rotors are made of cast iron not steel. Rotors act as a heat sink. Thicker and larger diameter rotors carry more frictional heat from the brake pads. During normal driving even though your foot never touches the brake petal, pads are lightly contacting the discs as you drive. This is to keep dust dirt and moisture off the pads and rotors.
If we were all lucky enough to have an optical pyrometer, you could quickly take the temperature of your brake rotors after a drive to see if both front rotors were the same temperature, and how closely the two rears matched. If both front rotor temperatures didn't match, the slider pins or calipers may be sticking which causes excess heat. Same with the rear rotors.
If you have sensitive hands, you could feel any difference in rotor temperature by opening both palms, 6" away from the street side spokes on your aluminum wheels and compare the heat with the opposite rotor.

Discs (rotors) will get hot in normal operation, but, if it's only the one getting hot then you may have sticking caliper piston or disc pad(s) seized in caliper housing and should be repaired A S A P
r doug w | Mar 20, 2010
Well lets see, you have a brake rotor approx. 14 inches in diameter suspended on the axle/wheel with 2-2x5 inch pads that compress upon the rotor to stop a 3000 pound automobile that going lets say 50 miles per hour. Friction causes heat. The pads are designed to withstand the heat, but they have no way of holding in the heat through the material they are built with. But the STEEL rotor holds onto that heat, after braking a rotors' temperature can be as high as 600 degrees. That's why there is drilled & slotted brake rotors to help dissipate the heat and brake pad dust build-up.
So, yes they are normally hot after driving. So hot that they will burn your finger if you touch it
A caliper that is frozen causing the brakes to be engaged all the time will heat up to the point of destroying the pads but not really damaging the rotors, so-to-speak. The rotors will become RED hot, and at most warp, then they are a problem, both in braking & drive-ability.

It is designed to take the heat. Rotors will last a long time if you replace your brake pads regularly and you ensure that your brake system is working correctly.
Jeremy | Mar 20, 2010
If no hot waves coming from the rotor it indicates normal. If you find any abnormal heat from on of the discs it indicates defective jammed calibre piston.Pl. do like this
1. Jack the front wheel and rotate. If it rotates freely with out any resistance then no problem
2. If both wheels resists to rotate freely indicates problem in master cylinder
3. There would be heat in the brake rotars if you run with frequent braking in traffic movement
4. This heat is due to self adjusting nature of brake pads.

they all get hot, as for the temp. degree, im thinkin a couple hundred
Heather - | Mar 20, 2010
If the heat is from stopping there is no problem - that is normal. But if one front wheel is hot and the other is only warm the hot wheel is probably dragging. That will show up as bad fuel economy and the brake will wear fast. I went through a pair of brake shoes in one month without even noticing anything wrong. I had forgotten to lubricate the slide pins in the caliper, which is necessary whenever the pads are replaced, and the binding of one of the pins worked like a ratchet to wear the pads down.
So if one front wheel is obviously hotter than the other a brake inspection is called for.

Can anyone tell me how to remove the front brake rotor on a 2004 Infiniti G35 sedan?
Nov 26, 2006 by stuart | Posted in Maintenance & Repairs
I have removed the caliper, pads and the caliper hanger, but the rotor appears to have been pressed on. Do I need to use a puller to remove the rotor?
If it doesnt have a screw in it you will either need a tool called a hub shark to remove it (I do not recommend trying that at home because most of the time when you get the rotor free you end up breaking the bearing at the same time) or you can remove the whole spindle and take it to a machine shop to have it pressed off the bearing and the new one pressed on. I recommend the machine shop a little more work for you but much less expensive the hub shark is a VERY expensive tool set.

How do i remove the 2 phillip head screws on a 2003 kia sorrento front brake rotor.?
Sep 26, 2009 by Bobby | Posted in Maintenance & Repairs
They do not want to come off. My efforts seem to be stripping the head off. I need a tip.
if they are stripped then you can use a small chisel and hammer to get it to spin by using the chisel to spin it counterclockwise. If you still have not stripped it you should use an impact screwdriver. You can purchase one at harbor freight,or Sears or tool supplier. it is used with the impact of a hammer to spin the screw with each hit. Once you get them off you can replace them with the tool, you just have to make sure you set thee tool for removal or installation. the tip of the tool is spring loaded to spin when hit.

Is the front brake rotor the same on a 400EX as on a 450ER?
Nov 17, 2008 by BK's Momma | Posted in Other - Cars & Transportation
the size of the brake rotor and brake reservoir?
they both are the very same rotor. the honda part number is the same also. and yes the master cylinder is also the same. if you order a master cylinder, the 400EX is cheaper and the same thing as the 450ER
