Please Help Cant Get Rear Brake Rotor off!
 
Ok as the title states... i cant get the rear brake rotor off.

This is what i did i took the e brake cable off and all other bolds to where the rear caliper assembly could just swing up and down for when you just want to replace the pads but the caliper assembly will not swing up enough for me to slide the rotor off? I thought to myself he there must be a screw or something on the pivoting caliper bracket so that i can remove the caliper assembly away from the rotor... but when i went to look at the area it looked like there was no screw there just looked like a deformed bumpy nub that barely stuck out?

Does anyone know what i have to do to remove the rotor when the whole caliper is able to be tilted?

The area Im talking about where it pivots is on the bottom pic below the arrow and behind the rotor? is there anything to remove in this are for me to get the rotor off?

Sorry for the confusion and yes i did search but i coulden't find anything really useful to my situation

Just look at it. Seriously. It DOES come off, dude. Stare at it for a few minutes and you'll figure it out, and then you'll feel better.

88RXVERT 01-23-08 09:22 AM

Are you trying to remove the rotor or caliper?

88RXVERT 01-23-08 09:28 AM

Wait have taken the screw out of the hub? That would help if not.

alexdimen 01-23-08 09:57 AM

LOL. You have to take the caliper bracket (the thing that holds the pads) off before the rotor comes off! There are 2 bolts holding it to the hub in the back.

Ummmmmmm - that deformed bumpy nub is what we refer to as a "bolt" There are two of them that need ro be removend in order to remove the caliper bracket to get the brake rotor off.

TitaniumTT 01-23-08 11:27 AM

By the way - your caliper is garbage - get a new one. O torn boot will let dust, dirt, grime and other things into the piston area that can lead to failure. A Reman one will probably run you $30 after core

Spectator 01-23-08 11:34 AM

LOL.

I mean. ROFLAMO!

Seriously ,You are working on the Brakes?..and you don't Know what the Heck you are Doing?..I hope you have good insurance..There are other people on the road too.you are Putting their lives in Jeopardy,along with yours....the brake is toast.Take the car to a Shop.I don't want to read about you plowing through a stop sign and hitting a Family of four.

evl mnky 01-23-08 12:49 PM

the ability for the caliper to swing up like that is only for pad replacement. The entire caliper assembly has to be unbolted and moved out of the way to get the rotor off....

And like others have said, your caliper is trashed, replace it.

enj01 01-23-08 02:44 PM

Ok for the record... thats not my pic i was using it for reference and i tried to see if the rounded nub thing was a bolt but it seriously is deformed looking and no tool can move it (i guess this bolt was messed up from the previous owner)

All i need to know was... is there supposed to be a bolt there or is it a pin the caliper assembly is tilting up and down on, and if so is that the bolt i need to take off in order to get the caliper assembly out the way?

And yes i did take the caliper out but just the actual caliper the metal tilting part surrounding it that is what i was having a problem finding out how this is removed

Yes i took the hub bolt out

After all this i think ive found a conclusion.... One of the heads on the bolts holding the caliper (the deformed nub) has been broken off.

I guess to make sure this is right ill compare the left side to the right side and see if theres a head on that bolt... if there is and the other one is indeed broken will a brake shop be able toget that out?

RockLobster 01-23-08 02:59 PM

please bring your car to a shop or get someone who knows brakes to work on your car with you the first few times........

You dont want to be messing with that alone if you have no experience...

at the very least get a haynes manual so you can refer to pictures and reference correct dissasembly procedures....

88RXVERT 01-23-08 03:05 PM

The so called "NUB" thing has me worried a bit as well and you may need help with that. Brakes are simple and just about anyone can do the job with minimal know how. Good Luck!

racerlinkfc 01-23-08 03:08 PM

isnt there a special tool that rotates the piston inward to push the piston back in ? just thought i'd ask ive looked all over for it .

88RXVERT 01-23-08 03:16 PM

Yeah any car parts store have them, looks like a little square with nipples for many kind of brakes.

i cant remember where i got mine, but before i found it, i always used a caliper compressor and a pair of channel locks being careful not to damage the boot or piston.works quite well

I dont know why everyone is saying i need to go get it done.... i reassembled everything and im driving it right now i just have bad brakes in the rear but the fronts are fine

All i need to know was if there was supposed t obe a head of a bolt where im having the problem... because if there is and i cant remove the caliper housing i cant remove the rotor due tho the housing blocking the rotor from being able to slide out

Ill just check my other side and see if there is the same problem there... if the other side has a bolt head then the previous owner obviously messed something up

ok this will clear things up a whole lot... wish i woulda found this b4 any way... this is he bolt i was talking about

http://img85.imageshack.us/img85/563...boltke1.th.png

On my car the previous owner broke the head of this bolt off (sigh)... does anyone think a brake shop can get that bolt off without the head? Being that the position of the bolt is in a tight area i don't think an easy out will work... so what will?

BTW i did buy the piston tool!

nvrdone 02-03-08 11:12 AM

Well, When I did my brakes I had the same thing happen; except that the hub bolts were stripped as well. So I just cut the sucker off. I was doing a 5 lug swap and didn't care if the 4 lug hub was ruined though...

Yes they can because i've done it, That same bolt sheared while I was undoing it. Had that horrible feeling when it's really tight then you can actually feel the bolt fail.
I drilled then used an extractor (basically a tapered LH die). Also heated up the area that the bolt inserts into. Plus a shit load of WD40. Came out easy.
At that stage i decided to renew all the bolts for brakes on every corner, Remember you need the actual mazda bolts or as i did went to the local fastner shop a bought high tensile bolts grade 9 or above.

TitaniumTT 02-03-08 01:13 PM

Does anyone else liken this kid to someone walking into an operating room to perform surgery on someone and not knowing what a persons leg is?

People who don't know what they are doing shouldn't be learning when it could cost someone else thier life.

enj01 02-04-08 12:52 AM

tomoaac thanks for the useful information it was exactly what i was looking for and I will be taking care of it this weekend because i have finally gotten a weekend off of work And i got a whole can of pb buster waiting for that bolt... or whats left of it lol

TitaniumTT dude you have seriously gotten on my nerves since day one because you think you know everything because you have been working on cars for however long and i guess you see that as a way to pick on younger less inexperienced people like myself, but when you really think about it ... how old are you? probably like 2x my age... anyway you do know a grip about cars and such and im sure you had you share of problems doing so also so why don't you go build your self a super car or something of that sort instead of bashing people on forums all daytomoaac

TitaniumTT 02-04-08 07:47 AM

I don't care if I've offended you or not, or gotten on your nerves. Yes I had to learn a few things and yes I did learn them before I took on projects like this myself. The fact of the matter is you cannot recognize a bolt when you see it. You have no business working on brakes without someone staring over your sholder. I'll say it again -

That's called reckless, dangerous & just plain stupid. The last thing I want to see is your inability to work on cars cost someone else thier life. If you die in a horrible firey crash alone than it's darwinism at work.
