Have just put the Ferodo DS2500 on my 328.
No serious driving yet but the pedal feel has improved a lot. Temp/friction variation seems to be very low so far.
I can also confirm that you do not have to screw the rear pistons back on 328 (as on 308 apparently) at least on late-88 328. The design is as on the fronts. Just push back.
Ciao

Thanks.
I have changed the front ones now. I had some problem to push back the right piston. The dust seal was also damaged so i believe that I'll have to fix it qiute soon. On the left side I pushed back the piston with all parts still assembled, i.e. used the old pads when pushing back the pistons. Worked good.
I also put some anti sieze compound on the pad surface as you said, Dave. :-)
I'll fix the rears on thursday.
Ciao

I have always just pushed them back in. Just did it again several weeks ago because I had to remove the rear right rotor to get the gas tank out to move the AC to get the cam belt cover off to replace forward cam belt. I pushed the pistons in by pushing on the pads so I could get caliper off rotor. |

Check that the exposed part of the pistons (under the dust seal) are in good nick prior to pushing them back into the caliper bore. If there is corrosion it will make short work of destroying the fluid seal.
I usually remove the lid from the fluid reservoir prior to the push back operation, it makes the job a little easier, but if doing this ensure the fluid wont go out over the top (it may well do this if the fluid level has been kept topped up in the period taken for the pad wear to take place). Get someone else to watch the level rise whilst you do the push back. If you need to remove some fluid either use a pipette, or suck it up slowly on a clear tube (be careful not to get a mouth full, it tastes bloody awfull!)
When pushing back, be careful not to damage the pad contacting face of the piston, even a slight nick with associated raised burr will result in uneven distribution of the braking force.
Don't know about F cars but fastening components for brakes, like suspension are usually treated with a locking compound. Clean the threads prior to applying loctite etc.
Regarding the pads, I usually relieve any sharp edges from the braking media with a file.
I also apply an anti seize compound like Copaslip to the NON braking but caliper and piston contacting areas of the pad back plate. DO NOT GET THIS STUFF ON THE BRAKING PART OF THE PADS OR DISCS. |

Thanks Lawrence.
Do I have screw back the rear pistons or can they be pushed? I believe you have to screw the 308 rear pistons.
Viao

And lastly, do not fill the reservoir before you install the new pads. Since the pistons have to go back in the calipers to accommodate the new pads, the brake fluid is pushed back to the reservoir. It'll come out the cap if you do this. |

Don't inhale the brake dust. Don't dangle the calipers by their hose. Torque the bolts. If there are spacers (mine has spacers) put them back where they are supposed to go. No special tools needed. You'll need to push the piston back into the caliper to get the new pads in. Piece of wood works; old pad works.
You might want to wear gloves. Your hands will get very dirty. |

I'll change the brake pads on my 328 -88 (no ABS) for the first time now (Ferodo DS2500).
Is there anything to think about before or when changing pads or is it just to go ahead?
Any special tools?
Ciao
