Guest sharon Posted February 14, 2004 Report Posted February 14, 2004 <_< HELPMY HUSBAND IS CHANGING THE REAR PADS ON THE GALAXY BUT HE CANT RETRACT THE PISTON INTO THE CALIPERTO FIT THE NEW PADS IN. RSVP Quote
Guest sharon Posted February 14, 2004 Report Posted February 14, 2004 tried that, stuck fast, but not seized, any more ideas Quote
iainkirk Posted February 14, 2004 Report Posted February 14, 2004 I'm sure you don't need to touch the handbrake other than to make sure it's not on. Retracting brake calipers always seems difficult on most cars, as you're pushing the fluid back into the reservoir. The TIS shows a caliper retracting tool 12-006 used to do this. Quote
Guest nimrod Posted February 14, 2004 Report Posted February 14, 2004 the piston has to turned clockwise while applying pressure to force it back into the caliper cheapest option is a big G clamp and a pair of pipe grips! use the G clamp to apply the pressure and grip the piston on the section above the rubber boot on the piston and turn it as it starts to return apply more pressure till its fully returned back in the caliper and DO NOT allow the old crap infested brake fluid to return back to the reservior release the caliper bleed nipple and drain the excess fluid from there, the last thing you want is dirt and crap travelling back through the abs pump/valve block! thats if you have abs?

Guest nimrod Posted February 14, 2004 Report Posted February 14, 2004 You have to have the handbrake off methinks, use a large screwdriver and gently lever the pistons back. Make sure the vehicle is safe to release handbrake (put in gear and chock wheels if necessary. Also make sure he avoids the rubber gaiter/seals. Watch the fluid level, if its been topped up it could overflow when he pushes the pistons back!! If all else fails, unscrew the bleed nipple a bit and allow fluid out while pushing back... wait a mo.....I think you have to disconnect the handbrake cable or adjust it right off...... you work for KWIK FIT ?

Guest Turbo Posted February 14, 2004 Report Posted February 14, 2004 If the piston has to be turned while going back in is there a tool available from Ford ? Quote
fozzer Posted February 14, 2004 Report Posted February 14, 2004 Yes there is a tool available, probably from a good parts shop.Don't make the same mistake I did and screw it the wrong way, the piston came out of the cylinder and spilled fluid everywhere!! you can turn it with molegrips if you are stuck.

Guest Andy Posted February 14, 2004 Report Posted February 14, 2004 you work for KWIK FIT ? NO NOT ALL KWIK-FIT PEOPLE WORK LIKE THAT.You can buy a good sykes pickavant tool from HALFORDS for around Quote
Ivor_E_Tower Posted February 14, 2004 Report Posted February 14, 2004 Read something 2 days ago that said you have to undo the bleed nipple to push the piston back if the vehicle has ABS, due to "blockage" in brake pipe caused by ABS valves. As almost all Gals have ABS, this is almost a certainty. Also as has been pointed out, ensure that handbrake is off! Can't really be a necessity to rotate piston to fit new pads, otherwise when releasing the pedal after normal braking, the piston would need to rotate for the pads to clear the discs??? Quote

Guest sharon Posted February 14, 2004 Report Posted February 14, 2004 THANKS FOR THE GREAT ADVICE, TURNING THE PISTON CLOCKWISE WHILST APPLYING PRESSURE DID THE JOB, NO PROB, SPECIAL THANKS TO NIMROD, (ANY TIPS ON REMOVING BRAKE FLUID FRON BRAND NEW BRICK PAVING, NOT EVEN 24 HRS DOWN) Quote
Guest Andy Posted February 14, 2004 Report Posted February 14, 2004 Thats no problem at all after next week i will not be working for them due to ill health,although there are some greeeaaat bodge artists in some of those centres.NO OFFENCE TAKEN <_< :angry: :angry: :angry: Quote
ridway Posted February 14, 2004 Report Posted February 14, 2004 Laser tools, available from good motor factors part No 1314. The caliper piston has to be wound in as it is pushed back because, unlike the front ones, it is on a threaded shaft which allows handbrake self adjustment for pad wear without the need for h/b cable adjustment. The job can be done using grips as mentioned but the tool really does make the job very easy to do. Retails about Quote
Guest Andy Posted February 15, 2004 Report Posted February 15, 2004 Yep thats the one BE AWARE the sykes tool has a square end so you can add to the tool for different ends (DIFFERENT TYPES OF CALIPER PISTONS).SOME of the other makes have a fixed end or is held on with a metal pin which in the past as i have found out SNAP.lIKE THE MAN SAYS AROUND THE Quote

Ivor is right You have to undo the bleed nipple and then push the piston back. Because of the ABS valves you have to then bleed the brakes in the usual way. Dulux Quote
