I need to know how to tell difference in disc brake mounts on my mountian bike. I am changing to a 8" rotor?

Unless you are downhilling 8%26quot; rotors are a waste of money. Nobody needs that type of power for XC or all-mountain.I need to know how to tell difference in disc brake mounts on my mountian bike. I am changing to a 8%26quot; rotor?
Its not always the mounts which are vital. you'll obviously need the correct mounts for the calliper.

the calliper needs to match the size of the rotor.

IS mounts are holes perpendicular to your wheels.

Post mounts are like holes drilled in you fork lowers.I need to know how to tell difference in disc brake mounts on my mountian bike. I am changing to a 8%26quot; rotor?
Well, unless you have a disc-equipped bike from the 1990's, you won't really have to do anything except buy 1 or 2 8%26quot; rotors and their accompanying calipers and hubs. It would also be wise to check and make sure your fork and seatstay will be able to handle the increased stress loads which a larger 8%26quot; rotor will produce, otherwise they can crack and fracture when riding. If you have a disc-equipped bike from the 1990's, you may need to get a more modern hub, because modern disc brakes have 6 bolts that attach the rotor to the hub. 1990's bikes can have any number of bolts, not just six. If, by chance, your 1990's bike does have 6 bolts, then all you have to do is read the above instructions. Otherwise, get a more modern hub. I hope this helps.

How to change rear brake pads and rotors in a 99 Olds Intrigue?

mainly the rotors, the pads should be easy...How to change rear brake pads and rotors in a 99 Olds Intrigue?
Rotors are hard to take off. They have something similar to a bolt on them that holds them in place. Sometimes they can get stuck. id suggest getting a strong man to help you

My car is giving me a headache any advice would help.?

This is my original question.....

I have a '92 Nissan Sentra 1.6L Manual Transmission. It has started to Idle really rough and drive rough as well while driving until it gets up to speed. I have put new spark plugs and wires, has a fresh oil change and everything. A friend of mine taught me how to check the spark plugs and listen for the change in pitch all but 1 changes and that is after the new wires and plugs. Checked to make sure everything was done right but still doing the same thing. Any ideas of what else?



So far I have a new distributor cap on it now, new rotor. No change. Still nothing in the one cylinder. Somebody also mentioned to check the compression in the cylinder. Now is that only something a mechanic can check with proper tools or is it easy to do.My car is giving me a headache any advice would help.?
Checking compression is easy, and your local parts place has the tool you need to do it. They aren't that expensive. It goes in place of the spark plug; you crank the engine a few times and see where the gauge tops out. It should be within about 10% of all the others; if it isn't you may need valves or rings.



But before you blow some money on that, try this: take out that one spark plug, shoot a teaspoon or so of oil into that cylinder, and put the plug back in. Fire it up. Did that fix it? If so, it's rings. And no, that %26quot;fix%26quot; won't last.My car is giving me a headache any advice would help.?
You can purchase the tool to check the compression in the cylinder.... it goes in place of the pasrk plug and can tell you whether t is good or not. You can find it at any auto parts storeMy car is giving me a headache any advice would help.?
this same thing happened to me on my truck im pretty sure that a couple of your injectrues are going bad in itMy car is giving me a headache any advice would help.?
assuming you checked for spark at that plug, than check that your getting fuel to that cylinder.



When you do the compression check you must pull all plugs out and disable the ignition and fuel injection. Also make sure you have battery fully charged.My car is giving me a headache any advice would help.?
well when you changed the plugs were they all a nice light brown color or were they black with abuild up did you have any that were white did any have a build up across from the tip to the electrode? i ask because this would be what you check to help determine problems if any with your engine also did you change the air filter compression test=compression tester =autozone, three squirts oil crank over about 4 times write down repeat for all cylinders all readings should be within 75%of each other next get long screwdriver put handle against ear other end against injector listen to see if all working good luckMy car is giving me a headache any advice would help.?
mostly could use a tuneup through a Nissan dealership

Is there a site that will tell me how to change my brakes and rotors?I have a 96 Mazda 626 and no manual.?

Brakes and Rotors are almost all the same on all vehicles. They are pretty easy to remove, but putting back together takes alittle more work.Is there a site that will tell me how to change my brakes and rotors?I have a 96 Mazda 626 and no manual.?
If you create an account at Auto-zone, you should be able to see the on-line repair manuals.

I have a ford explorer and my front rotors are rusted on, how do I get them off?

I bought the car a little over 3 years ago and I have never replaced the front rotors and I tried to change them but the rotor is rusted on. How do I get the rotors off without damaging the car? Only serious suggestions please...I have a ford explorer and my front rotors are rusted on, how do I get them off?
Wait until they rust off. Or torch them off.I have a ford explorer and my front rotors are rusted on, how do I get them off?
Spray penetrating oil (like WD-40) around the inside. Wait for awhile and then tap from behind with a mallet, or kick both sides from the front. You won't damage the spindle and if you scar or damage the rotors who cares, right?



If all else fails, use a wheel puller. You can rent one at a tool rental place for like $5.00.



Good luck!

chisel/elbow grease/ or mechanicI have a ford explorer and my front rotors are rusted on, how do I get them off?
bang on it with a rubber mallet after you have removed the wheel. it will start to come off at an ange then start banging on the other side. I have a ford explorer and my front rotors are rusted on, how do I get them off?
tie off your loose brake callipers with wire or a hanger etc and then use a hammer tap it at back at top then bottom and keep tapping it all around the rotor it will end up coming loose.



Hope that helps and best of luck.By the way if you do spray them be sure you allow several hrs for the spray to work its way in and soak the whole centre of the rotor back and front but be sure all the new rotors and pads are away from the work area, also be sure if you change the rotors to change the pads and to clean the new rotors with brake cleaner before installing , plus clean any parts you may have touched when installing the new brakes.

Rotor Question-PLEASE HELP!?

I've basically worn my brake pads down to the bone; my car makes a pretty loud grinding noise everytime I brake, although I haven't noticed any %26quot;spongy%26quot; feeling in the brake pedal or shaking in the wheel. I don't even have to press the brake pedal all the way to the floor when I brake.



I know I need new brake pads, and my dad insisted that I needed new rotors too due to the metal-on-metal grinding, but I just looked at the rotors and they look pretty good! There is some rusting on the outside edges and in a few other patches, but no deep grooves. The rotors kind of look like records-you know, those strange old things that grandmas and grandpas used to listen to. I couldn't check their thickness, but I've never had these ones machined before, so I think they should be in pretty good shape.



My working knowledge of cars is generally pitiful, but I'm pretty sure that I can figure out how to change my brake pads on my own.



So my questions are



A) Can I change my brake pads myself and leave the rotors as they are without any dire consequences?



B) If I take the car to a mechanic to have the pads changed, do they normally machine the rotors when they change the pads as a part of the service? One place quoted me about $160 to change the brake pads, but I forgot to ask if machining is included and now its too late to call back.



C) Can I save money if I just change my own pads, then take the rotors to a mechanic to machine? If so, what would the general cost be for my two front rotors?



Also, I drive a '98 Ford Explorer, 2WD (I'm pretty sure its rear-wheel).



Thanks for any input!Rotor Question-PLEASE HELP!?
It's dire because none of us can measure or inspect the rotors. The rotor friction contact surfaces must be flat and parallel and measure above the discard thickness. Any auto-parts can tell you what the minimum allowable thickness is. You can measure the thickness with a 0-1 micrometer or a vernier caliper. Prepare to be hozed if they want to sell you rotors. Inquire how much they are and where they were made. Off-shore brake rotors can be purchased at any auto parts-store for less than $35.00. Thy are made of terrible quality of cast iron. This is a wake-up call cause chain brake shops, private mechanics and new car dealerships install these cheap rotors and charge you premium prices for what you could by the best brands for.Rotor Question-PLEASE HELP!?
Whenever u do brakes u should either cut the rotors or heave then replaced the pads need a new surface to wear into or else the won't last Long and since it's an explorer it would be cheaper to just replace them I charge45 to cut when neW ones are only 25 eachRotor Question-PLEASE HELP!?
Ok, here's what I would do. Yes, you can change them yourself. Get your pads from Kragen's/Checker/Schuukcs(my favorite). Most of the do rotor and drum machining for something like $10. Buy the lifetime pads they sell for like $30. Have them show you as they measure the rotor thickness if they tell you that you need new ones. The %26quot;record grooving%26quot; you mention could go either way as faras needing new rotors. Some brand new rotors do not come factory thick enough to be machined even once. It all depends on the mfgr. And, it being a 98, how many brake jobs were done prior to now?Rotor Question-PLEASE HELP!?
yes it is rwd or 4 WD

i just replaced rotors on the same basic truck

the rotors can be had for around $30 a piece

call your local parts store (pep boys ,murrays, ETC)

there are 2 bolts that hold the brake caliber to the rotor get the proper tool at the same time

it takes about 45 min with simple hand tools

save yourself a few bux and buy a chiltons book and fix it yourself its really not so hard

you will also need a C clamp to compress the caliber once you have it apart

i am believeing there will be visable wear on the inside of the rotor

hope this helpsRotor Question-PLEASE HELP!?
A) you could do it yourself with a little bit of knowledge, but your rotors DEFINANTLY need replacing, rotors are suppose to be smooth, not grooved like records



B) if the rotors are still withing spec, they can be machined down, but if you ground them under their specs, they'll need to be replaced. if they're charinging $160, they should be machining the rotors then, or else that's just a very expensive pad replacement



C) like i said, you can do it yourself, but there's a lot of things that could go wrong, i would recommend you take it to a mechanic. they'll have all the tools for the job, so you dont have to go out and buy extra stuff that you probably wont use ever again just for one job



and it is a RWD car ;)Rotor Question-PLEASE HELP!?
If brake rotors look like records you will wear you new pads out pematurely. The thickness of the rotor wether it looks good or not is going to make or break wether or not they can be machined.



If you take them to a decent shop/mechanic they won't turn them unless they measure above spec.



$160 to change pads sounds like includes machine work if applicable.
