Ok So as you can tell from the title im trying to replace the rear discs on my 2001 WRX and Its defeating me!

I replaced the front ones no problem so thought the backs would be just as easy! OH NO, Ok so got the calipers off and loosened the disc but it just won't budge/slide off!

I have also removed the the rubber plug at the back and tried moving the little cog with a screw driver but it seems to be tightening it up not freeing it up, So turn the cog the other way i hear you say? well you can't as there is a massive steel block right above the hole which prevents you from angling the screwdriver down. see pic below



Any ideas as i really don't want to have to take it to a garage? and need to get these discs on sharpish!

Thanks in advance

Thanks

Daft question maybe but have you released the handbrake?

If not. Let the handbrake off and the discs will pop off nice and easy.

The rubber bung you are on about is the handbrake adjustment.

m8x1.25 bolt through the 2 holes in disc , screw them in to remove disc on a classic , i expect its the same

Only if the handbrake is released. :-)

CLR7

Yeah Handbrake is defo off! I thought it may have ceased on but the wheels are turning.

Do as madscoob says then dude. Make sure u have not adjusted you handbrake fully

CLR7

I'm worried if I do that I will damaged the shoes and springs inside? Which will cause more damage and expense!

if there is a lip on the inside of the drum catching on the handbrake shoes , forcing the discs off screwing bolts into the threaded holes WILL damage the shoes , springs and clips , this is NOT the way to remove the rear discs.

I have bent a flat headed screwdriver for loosening off the handbrake adjuster , you can get at it easily then , you usually have to slacken them off to remove the discs.

If the disc is stuck on by rust , then yes fit two bolts in the threaded holes to crack it loose , or give it a tap with a mallet to 'break' the seal

Hope this helps

The best way to slacken of of the hand brake is inside the car at the leaver under the centre consol there is an adjuster there. Well there is on a classic anyway

Same on a new age for handbrake adjustment.

Godspeed Brakes

No it is not , that will only slacken the handbrake cables , not the shoes , if you slacken the cables only , the shoes may still be too tight to get the discs off.

P1 Daveyboy

If the adjusters at the disc are seized I agree but if they are not surly it will release them ?

Godspeed Brakes

How will adjusting the cables slacken off a seized shoe adjuster ? if its seized , its seized.
The correct way to fit handbrake shoes and set them up , is to adjust the shoes so they nip onto the disc , then slacken it off slightly so you can feel its just about to drag , its a bit fiddly to do , you need to turn the disc left to right to feel it , once you have done both rear wheels , you then need to adjust the handbrake cables on the back of the handbrake lever to take up any slack on the cables , if your lazy , or a crap mechanic then you would take up all the slack on the handbrake cables and not bother adjusting the shoes as you should do , if this is the case , then yes , by slackening off the cables it would loosen the shoes enough to get the disc off.

My advise above assumes that they have been fitted properly in the first place

Cheers Ian

I think its all down to slackening off the shoes but that little cog at the back is really hard to move, I had to hit the screwdriver with a hammer to move it, and bending a screwdriver is harder than it sounds, any tips on screwdriver bending?

I had a look inside the car but getting to the handbrake adjuster is quite tricky as the casing around it is one big mould that goes from the bottom of the stereo housing to the centre glove box.

I'm beginning to think i may have to send it to the garage at least they can get under the car properly to take a look, although this is last resort.

I will give it one more try today to see if i can get these bloody things off but im not holding out much hope.

Yeah, use a cheapo one, those always seem to bend when I don't want them to

As Ian says, bent 6 to 8 inch flat bladed screwdriver (cheap one from poundland will bend easy as, just try lifting the corner of a 3x2 concrete slab)

If you have adjusted one way then it will reverse ok

see here https://www.scoobynet.com/wheels-tyr...rake-disc.html

and here https://www.scoobynet.com/general-te...c-removal.html

and ifyou use the search button you will find countless stories of the damage caused by using M8 bolts to jack the discs off without properly slacking off the handbrake shoes.

good luck

If it moves one way but not the other , then it cannot be seized , it might be adjusted all one way , to the loosest setting , and it has been adjusted up on the handbrake cable , so you have loosened it off all the way until it runs out of thread and not moving any more , and someone has tightened the cables up which is not loosening the shoes off enough , ie , lazy or a crap mechanic !

How many clicks does the handbrake lever come up ?

If it's just the shoes stopping the disc comming off then you should be able to move the disc off a few mm til the shoes stop it, if it is the shoes that are the issue the little cog is the way to go, I spent about half an hour laying under my car trying to loosen the shoes off 1 disc/drum it is fiddly and it does take a while but that the way to do it, once you've figured out which way to turn the cog (I can't remember myself) it'll be easy after that.
Ok so if the disc is not budging even a little bit then your issue is the fact that dust, dirt and rust binds the disc to the hub. What I do is little squirt of WD40 round the hub and in the little threaded holes, hold the disc and give the center drum part of the disc a few bangs with a hammer while wiggling the disc, this'll break the bond.

Good luck.

Ok I have managed to bend a screwdriver (on 3rd attempt) and got the little cog moving downwards which has loosened the disc to the point of it dropping off but there is something inside that just won't let go!!

I can rattle it around rather a lot but something is holding on for dear life and its starting to p!ss me off!

I went to slacken off the handbrake cable from inside but i don't have 2 10mm spanners! *sigh*

I just for the life of me can't believe how bloody hard it is to get a disc off!!

Probably need more winding on the cog, if the inside of the drum has a lip worn into it it's probably just the edge of the shoe catching.

CLR7

I would try more winding on the cog but the little bugger won't move anymore!

CLR7

BREAKTHROUGH!!

Got the buggar off!! I had wound the cog to its lowest point hence why it wouldn't move, so had to get a drew driver down the side and just help the shoes of the disc and pop it came off!!

Only thing is 2 short stumpy springs came off with it and i'm not sure where they came from *scratches head*

Thanks guys for all your help so far. Now just gotta find out were the springs came from and then whack the new discs on.

Sounds like you have pulled the shoe retainer spring cups off. There should be 2 pins coming thru the back plate, thru holes in the shoes. Position the springs over thes pins and hold them down with what looks like a washer with an elongated hole in it.

Pretty sure that the above will be the parts you need.

As above , if you have bent those lock washers that hold the springs in place getting it all off , you should be able to bend them back being gentle so you can reuse them , they just fit onto the pins that goes through the backplate and handbrake shoes , fit the spring , the washer fits in place , turn the washer 90 degrees to lock it in place
