mind blank...4pot Q?

[dubbedup]

Im upgradeing to 4pots this weekend (as my brakes are creating disk rust! and I cant remeber off the top of my head whether i need to take CV nut off to take disc's off?

if i do have to take taht 32 mm nut off i have to put whole hub assmbly in. is there any difference between hubs wrx vs sti?

Cheers

undo caliper, remove, then remove disc. The Rotor is held in place by the wheel and the caliper.

sweet...i couldnt think if i needed to swap the hub over...but this clears it up, thanks koom.

As Koom said but...

get a BFH... sometimes the rotor sticks onto the hub and needs lossening

[dubbedup]

done a few now...just had a mind blank...i have complete cv's/hubs/dics etc...just wanted to be sure in case i had to end up swapping hubs over...does anyone knwo if 96 sti spec wheel bearing will be betterer than a 93 wrx...any improvement or did this just change at V7 onwards (bigger bearing)

you screw two bolts through the hub of the disc and itll pop off. I wouldnt use a BFH. Its loud when you have your head under there.

it was v9 on that had the bigger bearings.. (the real strong ones) I dont know if there was an intermediate step between GC WRX, GC STI , and pre v9 sorry

all good, i will just leave the factory wrx hub then thro my sti discs etc on...

Always use the bolt method. The BFH one works, but you can't (well, shouldn't) use the discs again.

I used the bolt method on my good discs, and on one of my front disc where it had been metal on metal, so i took to it with a hammer...munted the discs right up b4 it finally came loose.

[Swindog]

Just get longer high tensile bolts and wind the eff out of them. Easier than whackin em too.

she was all done and dusted yesterday, much nicer braking (altho i was down to metal on one side) it feel like there is quite a lot more travel in the pedal, i suspect its cos more fluid needed due to the additional clylander?

[Swindog]

Just bleed the heck out of them and fill the master right the way up.

done...

Did the pedal come up better?

[dubbedup]

hasn't really changed it, but they work fine stop on time every time etc...

[Swindog]

must be ok then. Youll feel it better if you get some heat in them. Brake cylinder brace will increase the feel or pump them once or twice as you brake.
