fd brake rotor replacemnt

[james01uk]

hi

can anyone give me any details on how to replace the front and rear brakes on an fd?

i have the two small screws out and the calipers off
but i presume the hubs needs to come off.  If so do you know how to remove the cap in front of the hub nut?

thanks

iluvmyrx7 is not working :-(

How much of it are you replacing? surely even putting new calipers on would use the standard caliper mounts? or do you have new mounts to go on?

Have any pics of the offending area?

The break rotors (i.e. disks) are sometimes a real bugger to get off but once the calliper is off not too bad.

There should be a bolt through the rotor into the hub, this is just for keepin git in place when the wheel\'s off and not important in terms of safety.

I had to drill mine out as they were welded in place but you may have more luck.

Once out the rotors still wouldn\'t budge, this was because they\'d rusted/welded themselves to the hub.  Don\'t get too carried away with the hammer but a few gentle taps shoudl free it up and bob\'s yer uncle.  

No need to undo the hub centre.

take the calipers off (which you have already), unscrew the extremely annoying large cross head screws that hold the disks on, remove disks. If they won\'t budge, tap them with a hammer until they do (they may be rusted on)

I need to type quicker :2Confused

(I had to drill mine out too )

I find it best to leave a wheel nut or two loosely on the studs while hammering ... stops the disc falling off when it does come free

That\'s cunning Mike

[MikeLMR]

you think about these things after a million and one times of having stuff finally come off and smack into you. (steering wheels are best ... ouch)

I drilled the head off and swapped them for a hex version, can get a descent size bar on it next time i need to swap the discs over. There is another threaded hole in the disc, thats where you wind the bolt in to crack the disc off the mounting hub. Easier than a hammer, plus i smacked mine quite hard an it didn\'t want to budge  :Hammer

Erm, confused, when I take the rear caliper off the brake disc is free to just pull straight off. infact it\'d fall off. whats the score here about screws holding the discs in place? or is this just the front discs? Have I a screw missing or something making me think thats why my caliper is seized?

Cheers

Dave a previous owner more than likely rounded the screw off and drilled it out or just got rid of them cos they are a pain in the ass.

The screw has absolutely no effect on the performance of the brakes once the wheel is bolted on, if I understand correctly its just to stop the disk falling off when you undo the calliper? It not usually necessary cos the disk jams onto the hub anyway most of the time.

[davegttph1]

well, suprised at that, the heat coming from the disc witht he caliper seized Im suprised the disc hasnt welded itself to the hub or wheel etc...lol Not even seen any holes for the screws though, they re only held in place with the caliper.

Ohh well if it doesnt matter then fair enough.

I just used an impact driver, one good smack from a hammer and the screw came free.

Some after market disks dont have the pre drilled holes for the locating
screw  I have found. I\'ve always cracked mine off with a bolt winding
in about 1/8 th turn at a time and tapping around the bell part of the disk
then another 1/8 th and so on.You dont/shouldn\'t have to beat the disk off with this method, remember you have bushes and ABS sensors behind all that stuff you\'ll do your car a mischief if your not carefull! :Nono!

same as above, just done my front disks

1. remove caliper, support on block of wood
2. remove 2 large countersunk phillip scews, i started mine with an impact driver
3. look for small empty threaded hole in rotor hub, screw 1 of the large countersunk screws in there until it bottoms out
4. screw in half a turn or more so it is under tension
5. put the 5 wheel nuts back on the studs to protect them from the hammer
6. pull on the dics and hit each of the nuts in turn quite hard while turning the wheel stub
7. then screw the big phillips in again until it is under tension again
8. repeat until disc pops free

the disc seems to be on some kind of taper? so it has to come off near straight. the trick is to move the edge out a little then turn the disc a little and move that part out etc etc etc   eric e
