Can someone explain me the difference between those 2 calipers?

[ronenfe]

I don't even have c066 or c067 or s066. I have c063 but the current caliper I have looks like this one and not as the c063 in the file.
I have Twingo Easy 95, maybe they used different calipers there? mine is written Lucas on it, how do I know which one I need? what's the difference?

Perhaps someone replaced the Bendix brake with a Lucas.
Thats o.K. because the Lucas is way better.
Keep in mind that you need the 12mm disks and not the 8mm ones.
Look, you can even upgrade to vented disks http://www.twingotuningforum.de/attachment.php?aid=3980

Thank.

I don't think any previous owner did such a massive job on the brakes, I bought it when it was 12 years old. But maybe, if it's not possible Renault switched to these brakes for the c3g Easy 1995.
Anyway I've already replaced the disks a year and a half ago with the 8mm because I didn't know I don't have a c3g system, Is it a problem besides wearing faster?

I read in www.onlinecarparts.co.uk the difference between the 2 calipers:
7701201965 is Inner width [mm]:66,5
7701201769 is Inner width [mm]:58,5

I'll check the inner width of what I have and order the same.

The Problem with the wrong disks is that the brake pads might get stuck between the calipers and the disk once they are worn.

66,5 mm is for ventilated disks, not your business.

[ronenfe]

Yes, I measured it and it's 58.5mm.

Do you think it's dangerous to be with the 8mm? last time I replaced the discs when they reached 7mm, I'm not even sure they were 12mm originally. I didn't have any issue. I read the 12mm minimum thickness is 10.5mm.

[ronenfe]

Is there a manual for this kind of brakes? The manual I have mr305twingo3-section30-37.pdf shows only the older type.

Looks like Renault 5 Haynes book has the info, it looks like the same as a Girling caliper.

Hi, I am now replacing the disks and pads again and I bought the thick disk this time but I can't fit the caliper mount over it. The sliding pins are too long and I can't fit it over, I don't know why, either this caliper is not designed for this disk or the pins are not original and too long.

Man kann nicht einfach zwischen der massiven und der innenbelüfteten Scheibe wechseln.
Nicht in die eine und auch nicht in die andere Richtung.
Punkt.
Aber das hast du ja jetzt gemerkt.

Hi. It's not the ventilated disk. It's a solid one which should fit the lucas caliper, it has 12mm, and the two pads are 18mm each, total is 58, i'm missing 3.5mm of slack because the pins are too long and reach the end of the housing. I measured the pin length.

[ronenfe]

Here at Metzger catalog, it says the pins should be 72mm. https://web.tecalliance.net/werner-metzg...roups:1165
I don't understand then why I'm missing the distance, maybe the carrier is wrong.

Wenn der Sattel selbst über Beläge und Scheibe passt, dann verstehe ich das nicht.
Ein Dickenzuwachs von 4mm würde eine seitliche Auslenkung von2 mm bedeuten.
Da sind die 3,5 mm Länge zuviel schon nicht plausibel.
