    So just got back from France where we rode Metabief Bikepark, was amazing! However my rear brake was sticking on, so decided to look at it and follow Henry’s GMBN guide for tweaking brakes.

    Spent best part of two hours cleaning, lubing, cleaning lubing each set of pistons at a time. Went to put it all together and the actual pad retainer bolt housing with the thread….snapped! Brake now useless! Front one’s in bad condition too really as housing that feeds the brake pipe to the caliper also very corroded so from wanting to tweak I’ve ended up needing a full brake set! Not getting SRAM’s again, some form of Shimano 4pot I think!

    This is also all after spending a few hours on both our bikes cleaning them too making them mint as not had a wheels out wash in a while with it being summer.
    Basically today mostly wasted 🤨

    A day playing with bikes and spanners isn’t wasted

    Sounds like two small replaceable parts to have them working fine again? Maybe even someone has an old set to salvage (I’m nearly there, but mine won’t die after 7+ years do far).

    But If you’re intent on binning them I’ll take them for a pint and postage?

    I understand the frustration, but is this a opportunity to stick some Code calipers on it as a cheaper way of sorting it and upgrading ?

    If they are not too old you could check warranty ?

    I appreciate brakes a tribal thing but some of the other brands have their own issues and the grass is not always greener.

    Very true regarding not time wasted, I mean I’ve never really properly fiddled with brakes but I had all the kit so thought I’d try as the shop bled them in Metabief but it didn’t fix the issue. It’s great ti have learned how to do it though.

    Not sure they’re small parts, as it’s the housing on the caliper that’s snapped so the bolt has nothing to secure to = flappy pads.

    SRAM’s just seem so fiddly to bleed, I have the kit but last time it didn’t go to plan.
    In France the Guide RS Levers internals swelled in the sun too, so I still had brakes but an awful lever.

    I think the Code caliper idea Mr Binman is a great one to be honest.

    I was thinking of selling the bike on maybe in a years time so didn’t want it ending up being a parts bin special (capra Al comp 2017) and have always kept the bike as “original” as poss when things needed replacing.

    Also wondering how I stop this happening again?
    So I don’t wash the bike too often, the metal around the brakes has obviously become brittle, I got dot fluid on them once but as mentioned in guides washed off with water.

    Also after a wash I dry the bike off but not usually bolts. Best to get compressed air can to dry those bolts/areas like brakes out?

    Yes as per pic I even put brand new pads and was going to put my new disks on until I noticed the metal on the caliper was missing.

    As above Code caliper or I would buy the cheap Guide REs which come with the older Code caliper Can be had for £80ish per end

    If you act in the next four hours STAGE20 on Probikekit will get you a pair of REs for £138

    No problem. It works as I’ve tried it

    SRAM’s just seem so fiddly to bleed, I have the kit but last time it didn’t go to plan.

    We are a committed household in the sense that the only brakes we run are Codes, so I’ve had to bleed quite a few sets over the years (stupid internal routing when fitting, etc).

    But, they really are easy & simple to bleed. There is a great old MBR video on the YouTube which was for Guides I believe, but I found it & used it a couple of times & it’s just become my bleeding process. It’s really quite simple & works well.

    Also wondering how I stop this happening again?

    Happened to mine too a while ago (2017 model bike ) but SRAM warrantied them.

    Couldn’t work out whether it was due to expansion of the bolt, over tightening, too much loctite it or catching them with a tyre lever when pushing the pistons back in. I suspect they were made too thin and it’s a design / manufacturing fault

    I bought some discounted Code RSCs (pre-BREXIT) while they were away to keep riding and then moved the the Guides onto another bike / spares box.

    I have some secondhand Code RSs that just keep working maintainance free  while the RSC need bleeding more often.

    Code REs look like a good option but if you want to move off SRAM these look ok https://www.merlincycles.com/shimano-slx-m7100-front-and-rear-disc-brake-set-179619.html?utm_source=PHG&utm_medium=AffiliateMarketing&utm_campaign=phg-GB&source=PHG&utm_medium=Affiliates&utm_campaign=genieshopping

    I have a set of XT 4 pots with finned pads I need to sell if interested. Come off a new bike. Only used a few times.

    Bit OT but since SRAM started with the Bleeding Edge stuff, its super simple, fast and clean.

    Yikes I didn’t find it simple, wonder if it’s because I had an epic bleed solutions kit rather than original SRAM.

    Thanks SaintSludge, I am going to go Shimano so just weighing up my options but will be in touch if I choose to go down 2nd hand route

    Binman, really interesting! I know how I did mine, they’re years old and plastic tyre levers wouldn’t push the pistons back so I used ones that had a metal core in them but plastic on the outside. Honestly once I’d even finished Henry’s trick two back pistons were incredibly lazy to the point of. It coming out without being forced so they’ve clearly had better days!

    Those SLX’ look incredible value for money, I wonder if they’d give me the power I need but based on reviews they seem very impressive likely due to the larger 2 pistons I reckon!

    New 2 pistons have to be better than poorly/average performing 4pots at the end of the day!

    That or swap the pistons out for Code aluminium ones.

    Thanks Jim, the issue is the pads can’t be retained in the caliper anymore as the caliper body has broken. Just looking at 2 pot SLX and trying to get to the decision of spending £100 more and getting the 4 pots because I do tend to like modulation and 4 pots seem to give more of that.

    I got the two pots last week as I couldn’t get on with the plastic one finger levers on the magura 4 pots.

    More than happy with them, seem as good as mt5 for power but less effort to achive it. My view was if I wanted more power could get a 4 pot front for 60 and have a brake et for 200. At the moment not going to bother. I’m pretty heavy on a Levo sl as well.

    Mine also came with the finned pads making even more bargainous!

    I bet a blob of silicone on that pin would mean that brake was fine.

    Premier Icon chrisyork

    Just picking up on this, do you think so? I mean that pin is just there to keep the pads in, but…. It’s a fairly important pin! I remember flying down a North Yorkshire moors descent and the face of my gorilla pad just flew off resulting in only one brake to stop! Having the same happen is not an experience I want to repeat and I’ve not bought gorilla since!

    Have actually just found set of 4 pot SLX new for about £190.
    Has anyone used bikeparts.co.uk before?

    Just have to make sure the hose is long enough for the back for a large capra!
