MG MGF Technical - MGF Rear Brake-pad replacement

As there is no eqivalent "Haynes" manual for the "F", does anybody know how to replace the rear brake-pads (without swearing)?.

pay your local small garage £10 and they'll do it for you.

Otherwise spend all sunday afternoon trying to get the piston back without correct equipment, and then go to the garage and pay them £10.

we live and learn.

I had fun once doing this: one of the sliding caliper bolts had seized, and promptly snapped when I attempted to remove it. Oh joy.

But in actual fact it is pretty easy to do- remove the road wheel, remove the lower sliding caliper bolt and rotate the caliper upwards, paying special attention to not snag, stretch or kink the brake hose. Then remove the old pads from the caliper.
The caliper piston, unlike the front caliper, is of a rotating design, so the piston needs to be screwed in (clock-wise) to the caliper (note the level of the fluid in the master cylinder- it could overflow when you do this, promptly removing the paint from the bulk head). Then reassemble.

The "special tool" that I used for rotating the piston was an edge of an old metal file... I'm sure that a little impro of what you have in your tool box will do the job equally well! ;o)

Takes about 20 min's, and that's both sids. Just remember to put some rag around the master cilinder!!!
As you rotate the piston the brake fluid will rize...
Only do one wheel at a time, fit new pads and then foot on brake 3 or 4 times and then the handbrake. This will return the piston hard onto the new pad...
Have fun. Paul...

Hi all,
when resetting the pistons against the pads by engaging the brake-pedal hard several times - be sure to engage the handbrake 2 - 3 notches. Otherwise You can end up with a very tight handbrake that will be engaging heavily from the first notch with nearly no play in the system.

Nice tip- thanks Carl- I'll amend the web page. :o)

<<so the piston needs to be screwed in (clock-wise) to the caliper>>

that will explain, why brute force alone wouldn't get the piston back.

thanks for info.
