Does anyone know of a guide for how to fit new discs and pads all round? and i mean a full guide with pics etc, i've had a good search for the last hour but i cant see anything that makes sence :)
I know how to use a spanner, (fitted my front mount, decat and a few other jobs in the past) but the only experience i have with hydraulic brakes was with my old downhill mountain bike, and that was just 2 bolts for the caliper, 6 bolts for the disc.

If there is'nt any good guides then i'll get one made when i do my brakes tomorrow, so even any hints or tips would be very useful! But also note that i dont have any specialist tools so i may have to improvise.

Thanks in advance for any help :D
 
you need a rewind tool to do the rear calipers. don't try to squeeze the rear caliper.

undo bolt take off caliper replace disc and pad. easy job tbh.
 
I'm planning on doing this this weekend, have done it on my previous cars, clip and integra but not sure if anything different here except for this wind back took for the rear piston!!
 
Whats this rewind tool? nothing that can be used instead of these ?
 
its a tool for rewinding the piston back into the caliper. and no.
 
It is possible to use a pair of pliers to rewind back the rear pistons, bit the tool is much easier as the front require a bit of force to push back in, brought mine from halfrauds for about £25. Also would recommend buying a heynes manual whe you are there! But to be honest it is just a case of unbolting and bolting back on! Good luck!
 
Thanks again for all your help! unfortunatly i spent the last of my money on the brakes and a K03s turbo so it might have to wait until my next payday if i need this tool :( i'll see if one of my mates has one lying around and if not then im going to cry! suppose i could just do the front ones for now? ;)
 
you can buy a little square tool from halfords about £15 i think. has 4 different patterns on it (not sure if it will do the audi rears)

or take a look on ebay might get something cheap on there

i paid nearly £70 for a 19 pc set
 
I just used some pliers on the rear. For the fronts I used a piece of wood with a hand vice (can't remember the name of them) was dead easy!
 
Thats the sort of thing i like to hear! how were these pliers used? :) do i need to grab and twist it? if so im guessing clockwise?

Got the fronts done today, ill get a guide up when i get a chance
 
You need snipe nosed pliers and there are two indents in the piston opposite each other, put the ends of the pliers in these push and turn until the piston is level with the boot. Give the boots a good check over before fitting. I needed new calipers on mine in the end.

Cheers for the advice mate, ill give it a go on my next day off! :) can you remember which was the piston turns? ive heard that its a different way on different cars :/
I had a advisory on my MOT that the rear passanger side caliper had a leak.. so that could be a new caliper job :(

Thanks Deeman88 <3
 
Turn clockwise mate :) watch out you don't pinch the boot.
 
I always use a g-clamp to push the piston, with molegrips to twist, works well. Just make sure you only pinch the very end of the piston and try not to catch the bpot.
 
If the pistons are free, you can just wind them back in with a pair of pointy pliers as described.

However if they're sticky you'll almost certainly need the right tool.

agreed with this. even with the correct tool mine was hard to wind back in
 
There's a company called big red on eBay that sell reconned original calipers and give you 30/40 back for your old ones. Works out at about 100 for both new calipers
 
My front pistons were pretty sticky so im guessing the backs will be the same, however i love superkarl's idea.. Mole grips and a g clamp ;)
My next day off is friday so i'll try then and see what happens, i'll just make sure i have a bit of cash in my pocket so if i get sick i can go buy a proper tool :)
@A3 T, i saw your guide before doing my brakes, it helped me in places but im a more focal kinda guy, need to see things in the flesh to get my head around them
