Thanks Ric...the rears had been done 5K miles ago, but the fronts need to be done within the next month or so. Appreciate the clarification.
I'll so the fronts plus bleed and replace all the brake fluid.
Thanks again Ric.

The procedure at:
http://home.att.net/~ferrari/brakes5.htm
is the ATE procedure for the 308 rear calipers (I know, I typed it [and the comments] in!). ATE is the OEM manufacturer for all 308, 328 and TR brakes.
The front calipers are very straight forward. No screws to turn, just remove the old pads, back off the pistons with an expander, install the new pads, bleed.
If the rotors don't need turning, the front job is 0.5 hr and the rears are about 0.75 hr. If the rotors need to be turned, add approx 0.5 - 0.75 hrs per rotor. |

Donny (or anyone for that matter), the instructions from the site you suggested...the questions and responses are a little hard to follow and he seemed to mix the instructions and tips between the front and rear brake pad changes.
Did you take any notes or consolidate the instructions from the site?
Thanks! |

For the fronts (and the rears), it looks like the complete procedure will be a combination of the info from the site Donny recommended PLUS the instructions from the Alfa site (THANKS PETER!!!) |

I'm only tackling the fronts right now...but here is the procedure for both from the Alfa GTV site:
Alfa GTV6 Procedure
From: http://www.gtv6.org/eurocar4.htm
Brake Pad Removal/Installation
The following procedures are conducted with the car raised on jack stands and the front wheels removed.
Front calipers:
� With a punch, tap out the pad retention pins and remove the pad spring. Withdraw the pads. With appropriate tool, slowly press the pistons back within their bores in the calipers.
� Inspect the caliper seats for cracks and leaks, Rebuild as necessary. Also, inspect the pad retention pins and spring for rust or damage and replace as necessary. If you choose to use an anti-squeal compound on the pad backing plates, apply it now. Also, if new or resurfaced rotors are not to be used, lightly scuff complete braking surfaces on all discs with emery cloth to remove any glazing.
� Install the pads within the calipers and re-install the pins and spring.
Rear calipers.
� Withdraw the pad retaining pins by first removing the spring clips.
� Back off the parking brake adjustment at the rear calipers until the cable is loose.
� The caliper adjustment screws can now be slowly and carefully backed off. The inner adjuster is rotated with a 7mm socket and extension. The outer adjuster requires a 17mm combination wrench and a 5mm allen wrench. It is important not to go beyond the limit stops on the adjustment screws. Stop when resistance is felt. Failure to do so will cause permanent damage and necessitate replacement of the caliper. Once the caliper adjusting screws have been loosened, the pads can then be removed from the caliper.
� The rear caliper seals should now be inspected for signs of leaks or damage. Leaking or damaged calipers will have to be replaced with new ones.
� If the brake rotors are not being resurfaced or replaced, the braking surfaces should be scuffed with emery cloth to remove the glazing. When replacing the brake rotors, make certain to remove all of
� the rust proofing from the brake rotors. Anti-squeal compound can be applied to the back of the brake pads if so desired.
� The new brake pads, pins, springs, and pin retention clips can now be installed.
� With the pads installed, it is now time to adjust the calipers. Rotate the caliper adjustment screws leaving a gap of 1/32in. between the pact and the rotor surface. Use a feeler gauge to verify the proper gap.
� Run in the parking brake cable adjustment until the inner pads firmly contact the rotor surface. Then back off the adjustment 1-2 rotations of the nut until the rotor turns freely.
� Re-check the pad-rotor gap to ensure that the distance between the pads and the rotors is still 1/32-in. Further adjusting may be required, Once the proper gap is achieved, the caliper adjuster locknuts should be tightened and the dust caps replaced.
� Pump the brake pedal several times to check- for operation and pedal feel. If anything appears awry, don�t drive the vehicle until the cause can be determined and rectified.
� After 500 miles of use, the calipers must be re-adjusted. The previous instructions should be followed, omitting the portions pertaining to the parking brake cable adjustment. The importance of proper brake pad bed-in can not be stressed enough. Failure to properly bed-in pads will result in poor braking performance caused by glazing of the pads and rotor surfaces.
� Accelerate to 35 miles per hour.
� Using light to moderate pedal pressure, brake to approximately 5 miles per hour without stopping.
� Repeat this procedure at least ten times, allowing 1/3 of a mile between each brake application.

Thanks Peter...I'll search the new for an Alfa GTV manual. Again, appreciative for all the help.
Unless absolutely necessary, I'm trying to do all the work myself. Thanks again. |

Thanks Donny...I was looking in the QV owners manual and they make it look like a ten-minute procedure. Appreciate the tips. |

Peter,
The rear 308 calipers appear to be the same as a Porsche 914, but I'm not sure if it's the 4 or 6 cylinder model, or if they are the same for all years. Are the Alpha rear calipers also the same as on a 308? |

The brakes are ATE, German made, the same as Alfa Romeo GTV 1977 onwards and GTV6. Get a hold of an Alfa workshop manual and the procedure is all there, (unlike the Ferrari manuals). Porsche also ran the similar ATE brakes on their cars, but unsure of what models. The most crucial item is setting up the handbrake on the rear callipers. Easy to do but a Porsche or Alfa workshop manual will spell it out to you. |

Got my pads from Nick. Can't remember the exact price, but it wasn't too much. The back calipers have screws, one for each piston, you turn that pulls the piston back into the caliper. Not a pain, but be careful removing the cover plug. It's very soft metal and the allen head will strip easy. The front doesn't have screws. I just used the old pad and a C-clamp to compress them back in.
I also changed the fluid while I was at it, again, no surprises, just like any vehicle. $375 sounds high to me.
Let me know where you want to meet Kelly. |

Donny, it akes ma about 30 minutes to change the front pads on my Ford f150. I understand that there is some type of screw you have to tunr to get the caliber back in. Is that a pain or what. Does it make it more difficult. A friend of mine is being charge $375.00 for the front pad and changing the fluid in the whole system.
let me know. Gt Car parts wanst $65.00 for the pads.
My tires should be in next week, if you can lets' me up.

Greg, this is about the best I could find when I did mine. If you have any questions after you look at this, email me and I'll try to help.

Does anyone have a procedure written down for changing the brake pads for 308QV...or any 308?
Or, does anyone have opinions (on this site???) on which book or reference manual has the best set of instuctions for doing this?
Appreciate all the help and guidance. |
