Brake Calipers
How easy/difficult is it to service brake calipers?
Do you need special tools?

Re: Brake Calipers
Not really, however if the pistons are stuck, there is a special tool to remove them, but I've never needed one.

Re: Brake Calipers
It's easier to work the piston/s out evenly while still connected to the system. Like most jobs it's handy enough if nothing is seized.

Re: Brake Calipers
I service my own calipers.
A quick service (without taking the calipers off completely or removing the pistons) is very easy. Squirt a bit of brake cleaner around, use a toothbrush to get in the narrow bits and a bit of fine sandpaper on the pad retainer pin.
If you want to remove the caliper/pistons completely you'll need a brake bleeding kit and as brake fluid is corrosive, you'll need to be careful.
There's some really good Youtube tutorials for doing it - shall I find you one?
What bike do you have and do you want to remove the calipers completely and change the brake fluid, or just give them a quick clean/new pads?

Re: Brake Calipers
Pretty sure nothing about this is going to be easy or simple, but I need to find garage space and get it working to save my sanity!!
I know I will start with the engine but till I get it in a garage and on stands I'm just thinking out loud - well, thinking on here!!

They'll have to come off as it will need new brake lines as well
It's been stood for years. I did the timing belt, plugs and filters 2 summers ago and then bailed on the engine due to no strength in one arm and a head injury (from cycling badly!!)
Totally understand about brake fluid. I've done quite a bit on bikes but, whilst I've done pads, I've never messed with calipers. And all my spannering (bar what's mentioned above) was pre Aug 14 2017!!
I'll ask for a tutorial when I've got the engine running!! LOL

Re: Brake Calipers
Oh, I'll be back here asking stupid questions. Been a long time since I've had a spanner in my hand!! Like I say, never messed with calipers before, just want to know if I need to buy something to make it possible to do the job when it gets to their turn!! LOL (When it gets to their turn I'll be asking pointers for the YouTube link!! )
Got new HT leads, need to find a battery, then see if the little bugger will turn over.
If it does, fuel lines, brake and clutch lines, a new (secondhand) tank and probably a host of other things!!
But if I don't get it running things will be quite difficult this summer!!

Re: Brake Calipers
Mechanicking isn't really my thing, but one bit of advice:
If there are twin discs, ensure that all four pads (not just three) have the friction material facing the disc.

Re: Brake Calipers
If it’s been sitting a while it might be easier just to buy an overhaul kit with new seals and pistons.
That way you just junk the old stuff and make sure the callipers and seal grooves are clean then bang in the new bits.

No idea of the quality of this , just an example.

Re: Brake Calipers
My plan had been to but the seals and take the callipers apart to clean/make sure the pistons are ok. TBF, the whole bike cost me £200 - I'm not overly keen to spend serious money on it just yet - although, I guess that is a kit for all three callipers? So you are probably right - I'll have a look at the callipers on the bike when I get to it next and decide thenScotsrich wrote: ↑Sun Mar 14, 2021 8:04 am If it’s been sitting a while it might be easier just to buy an overhaul kit with new seals and pistons.

Cool. I do have a bleeder kit though, or would this be better? (I'm still a little challenged on one arm, so need things to be easy for 1.5 arms!!)DefTrap wrote: ↑Sat Mar 13, 2021 8:51 pm These are excellent

Re: Brake Calipers
If you have kit you're comfortable with I'd go with that, just that these are great for a few quid. I normally prime the system by sucking with me big ol' lungs then finish off with the little bleed hose.Noggin wrote: ↑Sun Mar 14, 2021 9:40 am

Wowzers. Thank you. I kind of want to try and see if I can do it. But if it's above my skillgrade I may well take you up on that. Thank you, really kind of you

Re: Brake Calipers
fyi, your Monster might only have one front calliper, a lot of them were single disc.

Re: Brake Calipers
I do think it is single. But need to get to it to check. Probably will find out before I find a garage! Just so I can have the bits to hand for when (hopefully) I find a garage to work on it!!KungFooBob wrote: ↑Sun Mar 14, 2021 11:55 am fyi, your Monster might only have one front calliper, a lot of them were single disc.

Re: Brake Calipers
I had a badly seized set of calipers on my Thundercat so I stripped them and replaced the seals. It was a long time ago but I don't remember the seals costing a significant amount so that looks a bit pricey. The seals I took off were still in good condition so it may be worth having a look before spending that much.
The job was simple but getting the pistons out wasn't, it took wooden blocks and a G clamp to hold the other pistons in place while an air compressor forced a stuck one out. As long as it wasn't needed urgently it's one of those jobs that I'd do myself again.
