Caliper questions

Wow, I'm nowhere near that committed lol. Just maintained and functional is all I want. Just having had them apart makes me feel better as the last reciept I have of a brake overhaul was like 5 or 6 years ago, so I has no idea what state they'd be in.

Was expecting seized pins at least, but only trouble was a set of pistons which could have been avoided if I was better prepared.

Must get some gloves in the future though, my hands are ruined from all the solvents!

Ok, lets hope I used the right grease in the right places!

RRG smeared on the seals, and refitted.*
RRG smeared on the pistons and refitted (anyone else find that ultra smooth tranistion of a nice clean piston going back in really satisfying?)
RRG smeared on the sliding braket pins, rubber boots refitted

Used rag to wipe clean the face of the piston edge that contacts the pad

Smeared (liberally) copper grease onto back of brake pad (not the whole pad, just the metal shim bit), and slotted into caliper

Refit static brake pad without any grease - it just sits there right?

A dollop of copper grease pushed into the hole that the end of the pin goes into

Copper greased pin, slid it in, wiped excess copper grease from fingers over the R-Clip and fit that

Copper greased bolts and screwed them in and out a few times

So...did I do it right?

*The bottom seal which is supposed to be tapered - I either have the wrong seals, or the taper is teeeeny, becuase no matter which way I looked at all 4, I wasn't 100% on which face was wider. I guessed, but its very possible I got it wrong.

What are the consequences? How do I check this bit properly?

Also, was I supposed to smear any on the "Pad Spring"?

Ta!

AFAIK the "taper" on the seal is just a haynes ****up.

Oh, thank god. Spent ages staring it to death.

How about the other bits YC? Did I do it right?

Sounds alright to me.

Only thing you did not mention is outside of rubber boot which goes through caliper body... it is good to put some RRG on that as they can corrode there and stop caliper from sliding freely on hangar.


Yes it is also normal to find pistons sliding into place satisfying

Cheers!

I'll run some RRG on the outside of those boots as well before I fit them, after all this snow nonsense passes!

I'm well chuffed

another little tip i have been using for years is to put some PTFE tape (plumbers tape) on the threads of the bleed nipples so when you come to bleed the brakes the brake fluid wont rise up threw the threads giving a better bleed and has the added bonus of making sure that the bleed nipples dont seize the next time you go to bleed the brakes.

dont cover the bottom bleed holes with tape, you only need to cover 2/3 of the threads leaving the bottom part untouched.

make sure you wind the tape (hold nipple in left hand and wind tape anticlockwise with a fair bit of tension then just pull to snap tape) so it wont unravel when you screw them in.

you only need 2-3 turns of tape.

roll the threaded part between your fingers when you have applied the tape so its nice and secure.

oo thanks for the tip Bib!
