1995 24V - Lucas or Girling Calipers or both?

peglegtom · #1 (**permalink**) 06-06-2009, 06:24 PM

Just unpacked the front calipers I purchased from IAP. One is Lucas and one is Girling. Is this like the usual Alfa practice of using whatever was on the shelf or is one caliper wrong? CarDisc manual indicates brakes are Girling! The two parts look like the mountings, etc are the same, but other parts of the calipers have different shapes. Are these interchangable or does one need to be sent back?

Want to know before I paint them.

Thanks!

Girling front is a 54, Lucas Front is a 57.

Looks like IAP gets a nasty call on Monday.

Thanks!

Fortunately. At least I can continue to drive the car while this snafu is fixed.

The first person I talked to indicated that all 164 front calipers are the same and they only list 1991-1995, but if you check their website, they have separate part numbers for 1991-1993 12V cars and 1994-95 24V cars as it should be. He indicated that I should send back Girling 54 mm caliper and they would credit me.

Called back to check if they had any 57 mm front calipers in stock. Talked to another person. Told him my story, he also indicated that he thought all 164 front calipers were the same. Asked him to check to see if they had any 57 mm front calipers in stock. The came back and indicated that they have a Girling 57mm that they will ship to me. I specifically asked him to verify that it was a 57 mm piston and he confirmed that it was. Will charge me for another caliper and core charge, which will be refunded when I send the wrong one back.

I'll keep you informed regarding of what I receive.

When I look on IAP web site and in catalog I see the same numbers 05293/05294 for 91-95 front calipers and same repair kit 06517 for both, too.

I know now Lucas and Girling are the same company but my 91 has Girling on caliper and Myron/s has Lucas on his 95 so companies must have merged after that.

I wonder how much mismatch in braking force 57 vs 54 mm piston size will give?

Now front rotors do have different item numbers 06027 91 and 06034 94-95.

Here's a photo of my recent rebuilds. They are off a 94 LS , the rears are the same for all the 164's. The caliper mount bracket say's LUCAS on the other side.

They were rusted to the point that the pads were fixed in place.
The front were being used exclusively and did a good job with braking.

Now these rebuilds are coated with Eastwoods Crystal Diamond extreme clear, impervious to brake fluid and can take heat up to 600 degrees F. Hopefully they will not rust as fast.
