Replacing Front Pads/Discs Classic 4 Pots

Level of Difficulty for Pads and Discs
* *

Tools needed
17mm,19mm sockets
17mm Spanner
Breaker Bar
Rachet
Small extension Bar
Pinchers/Pliers
Brake Cleaner
Wire brush
Copper Grease
Flathead screwdriver
Small Lever or Piston Retraction Tool or G Clamp


Make sure car on level ground loosen wheel nuts not taking bolts off jack up car with trolley jack and secure with AXLE STANDS NEVER go under a car only supported by a Trolley jack


PADS
1)Take wheel off
2)Open Brake fluid cap cause this will allow later down along the line to push pistons back faster and also if you dont open cap have heard that you can blow cap off cause off back pressure when piston being pushed back
3)PULL little retainer pin here PIC.1 Then Pull 2 Larger Pins out with Pliers and retainer clip will fall out looking at where the pins go for re-installation PIC.2 you can force back the piston with a lever bar being carefull your not damaging anything then take Pads out. PIC.3 this is with caliper off might be easier to push piston back. Then take note the way Pads come out and the order then the Shims on the back of the Pads have a look at PIC.4 and 5 mine has 2 Shims put copper grease on back off New Pad then put the Shim with slots on then, then the backing Plate Shim to Piston Shim Put Copper Grease on these to as it will cause no Squeal at all or to a minimum sound
4A)You can then use a Piston Retractor tool or a G-Clamp but you will have to take caliper off for this but try to push the 2 pistons back at the same time as if you push 1 the other push's out or 4B)also what you can do is get a Flathead Screwdriver looking at PIC.6 and 7 this a good Lever point to push back 1 piston at a time to if doing this way it will not damage disc and keep an eye on dust boot on piston dont break it once pistons back a good bit the New Pads should just slide in fine then
5)Then put retainer clip in sliding the Large Pins through holes in the back of the Pads then put little retainer pin back in might need to twist larger pins to line holes up for little retainer pin MORE PICS NEXT POST PICS.15-17 then wheel back on close brake fluid cap and PUMP brake pedal before you MOVE the car, they will get solid and job done Pads take about 50-70miles to break in so take it easy
DISCS
You should always use New Pads when changing Discs to for them to bed-in properbly
6)Follow Step 1 and 2
7)Unsrew the 2x17mm bolts out that hold in caliper bit of brute force with these PIC.12 NEXT POST
8)Take little Retanier Pin out of the larger pins then taking note again the way the larger retainer pins x2 are fitted through the retainer clip take them out then with a bit of force caliper should slide up and off pads
9)Support caliper taking strain off brake pipe with cable-ties hung onto spring PIC.8
10)Disc might be hard to get off just bolt 2x8mm bolts into holes on disc screw them in evenly and disc will pop off then before you put new disc on PIC.9 good idea to clean hub with a wire brush PIC.10 and brake cleaner so it will fit flush when put on BUT before you fit New Disc clean it with White Spirits to get all oil off as they come with oil on disc to stop them from rusting while in storage
11)Match New and Old Disc to make sure same size
12)Put New Disc on Hub
13)Follow step 4A OR 4B but for 4B secure the caliper back onto hub carrier, no harm to put copper grease on 2x17mm bolts and tighten them tight to secure caliper back on hub carrier
14)Follow step 5
15)Once everything on and secure put back on wheel and put wheel on and put nuts on chris- crossed pattern as the wheel will go on through and seat flush to brake disc and brake disc to hub PIC.11 NEXT POST put brake fliud cap on PUMP the brake pedal till it gets solid and JOB DONE Discs take anywhere from 70-120miles to break-in so take it easy on the brakes. No hard braking you might see smoke from New discs to dont worry just break-in period but take it easy Takes about an hour but took me longer taking pics along the way

Just striped my brakes down just so as to see what pads are in use as its a new motor for me and the brakes are crap reckon pads are fried ( mintex with loads left) but i noticed from your pics that i must have Tarox discs or the like as they are drilled and groved (thats a plus), but thanks Darren for the tips on the greese as i'd always wondered where you'd get away with putting it, and i'll give your post another read when i go about replaceing the pads. thanks.

10)Disc might be hard to get off just bolt 2x8mm bolts into holes on disc screw them in evenly and disc will pop off then before you put new disc on PIC.9 good idea to clean hub with a wire brush PIC.10 and brake cleaner so it will fit flush when put on BUT before you fit New Disc clean it with White Spirits to get all oil off as they come with oil on disc to stop them from rusting while in storage
