Author Topic: What is up with the stupic c-clip for the rear wheel cylinders.  (Read 247 times)

So I installed new wheel cylinders last night and fought with the stupid retaining c-clip even with the "help" of the useless tool. My Volvo 122 rear wheel cylinders were bolted through the backing plate which made them way easier to install and were firmly mounted.
Has anyone modified the wheel cylinder with a couple of 5mm/#10 threaded screw holes to bolt it to the backing plate? I may give it a go with the old cylinders and see if it will work.

I feel your pain - in fact, we ALL do!  50.gif

However experience with this tool has taught me two things - you need to put grease on the cone so that the clip will slide down. Second, the curve of the clip has to face up.

After that I actually got it to work pretty well...

The other way I do it is to put a wedge between the cylinder and the hub to hold the cylinder in place, then bend one end of the clip up - then snap it in and take a drift and tap the bent end down, it will pop right into the groove.

Ya I did most of that except wedging the cylinder. I just find it a somewhat crude method for attachment.

You only have to wedge the cylinder to do the bent clip tap in method, and I agree that it sucks. Old Minis used to have bolt in cylinders too. They also used E clips, if you can find one the right size they work perfectly fine......

I threw the clips away and just used snap rings like the early cars had much easier.

What size snap ring, Jeff?

Edit:I measured the groove at 5/8", Home Depot has a pack of 10 for $4.39

yes 5/8 you can also buy 5/8 wave washer to go under the snap ring and keep it all snug or just put a slight bend in the ring or do nothing it'll be fine either way.

Do they rattle if you don't use a wave washer or something?

Yeah imo you need the wave waasher. it is loose if you don't have.
New wheel cylinders come with a roll pin which goes into a hole in the backing plate. My old backing plates did not have a hole so I took the roll pin out.

I drilled a hole for the pin to locate into.

The pin is the anti-rotation feature for the newer backing plates and new wheel cylinders. Mine were the older type with the two raised nubbins on the wheel cylinder side trapping cylinder and making the roll pin un-necessary. But it also makes the wave washer necessary to keep it tight.
