Re: Rear Brakes - help needed asap
It's quite easy- with familiarity.
Firstly, the rear of the car should be supported. Sometimes the exhaust can get in the way.
The rear pad retaining pins often seize and new one will be needed- new fitting kits are readily available.
The plastic caps on the sides of the rear calipers should be removed. The 17mm lock nuts loosened and then the 3mm (I think) allen key adjusters backed off until the pads are fully retracted. Do this gently and stop if they tighten up- your propbly turning them the wrong way. Check to see if the discs stop being easy to turn to check this. Use your fingers on the top of the pads to find out when the pistons are retracted.
The inner pad adjusters are the 7mm nuts on the rear of the calipers. Turn them to retract the pistons and pads in the same manner.
Clean out the calipers so the new pads fit freely- remove the discs if necessary. Remember to hammer the allen key socket into the bolts to remove the discs. Use heat and a shield if they are seized as you only get one shot at slackening these before you round the heads. Hold the driveshafts from turning with vise grips.
Slacken the handbrake cables so that there is no tension on the cable.
Fit new pads and sparingly lubricate with anti seize/ anti squeal compound. Tighten adjusters until they cause a LIGHT drag on the discs and tighten locknuts. Ensure that the locknuts do not turn the adjusters. You may need to use a hollow 17mm socket with an EXTERNAL drive and an allen key through the middle. Do not overtighten- all do need to do is to stop the adjusters turning. Refit caps. Adjust handbrake cable until freeplay is removed. Do not continue to tighten to reduce the handbrake lever travel- it will eventually self adjust to a preset level and all overtightening the cable will do is to cause wear at the top of the handbrake mechanism and prematurely wear the calipers.
Roadtest and ensure there is not excess brake drag and make sure the rear brakes do not get hot.
I suggest that removing the pads is a routine service item and should be performed once a year.
