Answered: Kadett 1.1L caliper needed in Vancouver, Canada

I think I found a new replacement caliper for the kadett 1.1 disk brakes.
Unfortunately my car is in Europe and I am in Vancouver, BC Canada.
I need a 1.1L caliper to be able to compare if this new caliper will fit.
Are there any members in this forum from Canada, or close enough to Vancouver, that have one of these calipers that I can borrow in order to be able to compare ???

Alternately, if anyone could measure up a 1.1L caliper and send me the measurements.

Paul

I don't know for sure, but, I'm sure someone will correct me, but, did the 1.1 Kadetts HAVE front disc brakes? I thought that was just the 1.5 and up?

Yes and no. The early small engine models (1.0, 1.1) were available in Europe with drums as standard, or discs as an option; and the later models (~71...72), and all 1.2 liter and up had discs as standard. I don't know about the US models, if the question comes up.

What dimensions do you need? You mean you have a different brand or different model caliper, and want to compare basic dimensions?
I can also check for you on German ebay, and even help with making the payment since almost nobody accepts paypal in Europe.

My coupe has disc brakes on the front, it's a '67.5 with a 1.1L, and so does my '71 sedan with a 1.1L. Looking at them, they look exactly the same in every way as the regular pre-'75 calipers except for having a smaller bore for the pistons.

Given that, I can't think of any reason to keep and use the 1.1L disc calipers myself. I'd rather swap them out with the 1.9L calipers for a little more brake pressure and a little softer pedal.

Wow thanks for the replies.
My Kadett is 1.1L with disk brakes.
I made a rough drawing of measurements I need.
I have included an attachment in jpg format of the drawing.

The idea is to be able to compare and see if it will fit and clear all relevant areas. So measure everything you can and let me know.

It needs some minor grinding to make it fit... well see, but if it works we would have brand new available calipers to replace the old ones.

Thanks Paul Silva

Not the Same!

I have a 1967 Kadett Rallye 1.1SR with factory disc brakes - the calipers are not the same as 1.9L GT ones. Both the puck (piston) size is different (45mm vs 48mm) and the distance between the two mounting holes is closer on the 1.1 calipers.

I tried to replace mine with 1.9L GT calipers and they would not bolt up. That means that the spindles the caliper bolts to are also different.

Did not measure anything at the time except to note that if you want to use the larger 1.9L calipers the spindle has to be swaped out as well to get them to fit - and that poses difficulties as well for the earlier ball joints are different too!

The discs themselves are the same.

This may help

measurement from a caliper that came off a 1.1 either 66 to 68 model Kadett. Not sure which one it came off of. There is no bleeder valve opening on this caliper. the Piston measured roughly 44mm as it is still in the caliper and could not get an accurate measurement. Hope this helps.
Jim is correct on changing out to a 1.9 caliper on a 1.1 equipped Kadett. Gene the 1.1 Rallyes had the disc as standard equipment, all other 1.1 Kadetts came with drum brakes on the front with discs as an option. My 66 Kadett was loaded with all options including the disc brakes.

I am not trying to install 1.9L calipers. The calipers I found are for a different aplication, and I think they are about the same as the 1.1L calipers
thats why I need the measurements.

I opened the attachment in Photoshop but I can't read the numbers its all too fusy. So I resaved the origional JPG as a PSD file and if you could insert the measurements again I would apreciate it.
You will have to go back to the old message and download the new format.


Thanks Paul

Thanks Killer Texas
Its enough information to know that it will probably work.
I will buy a pair and take a chance. I will report back to the forum with all the fitting details, it will be either this fall or next fall depends when I go back to Portugal.
