I need to know what size rotors I need for the front is a 4 wheel drive a2.7 V6

You don't have the option to use different sizes?


Just goto the parts store or look at their site, but the main difference is you have to know if that vehicle is 2WD or 4WD to get the correct rotor!

This video should help. It's a 2000 Silverado but is probably the same as yours.
2000 Chevy Silverado 1500 front brake pads rotors replace

Hello Harvey, My information shows firing order of 123456. #1 being passenger's front cylinder and #2 being driver's front cylinder.

Which cadillac? 4 Cylinder cars it's the one farthest from the belt drive. V6 rear drives it's the drivers side front second one back as are rear drive V8's. The front drive V8. is the second cylinder from the belt drive on the front side of the engine. Tell make year and model engine size (4.6, 4.9, 500 Cu in. Ect. and i'll tell you exacetly.

Don't know if you have 2 wheel drive, or 4 wheel drive...if 4 wheel drive Ford would only recom/mend the same size for the front...with 2 whell drive you can run a smaller front size tire...but don;t know why you would except for looks...:) The size smaller than the 235/75/R15 is 225/75R15 and next smaller is 215/75R15 and so on... A lower profile size would be 235/70R15 or 225/70R15 and so on...I would not recommend using anything smaller than these...the smaller sizes don't always cost less anymore...

you need to disassemble the four wheel drive unit then unbolt the rotor from the hub

Check the front axle solenoid. If you go to the parts store and ask for a 4X4 front differential shift actuator then you know what you are looking for. Common problem if it wasn't used much.

I am not an expert but yes i beleive you have to remove hub nut to get rotor off,also will need flat head screwdriver to unscrew internal nut before bearing.I also changed bearings while i had it all loose.

Have you a had a 4 wheel alignment done?If all four wheels aren't set to a comman center line it cause it to shake,a warped brake rotor could cause this also.

The rotor and hub assembly are held together by the studs,you must first remove the 4-wheel drive hub assembly,then the wheel bearing nuts,and pull the hub and rotor off as a unit. Next lay it(back down) on a piece of wood, using a drift punch drive the studs out. Turn it over ,lay it(face down) on a block of wood, line the new stud splines up with the grooves in the hub and drive them in with the punch and reassemble. A set of dentist style picks will be helpful with the clip in the 4wd hub and a 4 lug 4wd nut wrench will be needed.
