Yes its pretty normal for things to move when you yard on them, its all springs, cables and minimal amount of metal so its all got some movement, but given it generally moves with very little force it won't do that in operation
My rear brake cable keeps stretching... I know it's longer than usual (mid tail) but I'm starting to think there might be a defect in it.
@Spitko sure its not slipping at the clamp to cable on your brake?
I thought that at first, but the cable looks clean at the bite point
Motor stuck in BB, any ideas? Tried heating and penetrants.
are you keeping the frame
Hopefully
you could try a clamp, but it's tricky
because you can't push on the square crank mount I've heard
you'd have to to on the outside ring
then, the clamp would have to be long enough to grab onto a strong enough brace on the other side (you have to clear the other side of motor)
@NERO get a quite hard wooden block, cut in the middle so it fits over crank. Then you can hammer away at the wood
after some penetrant or whatever. no other ideas. But don't hammer the square crank no matter how tempting
other idea is, try flipping the frame upside down, get someone to brace it, and try grabbing the motor and moving it side to side. You have a lot more to grab onto unlike trying to push it away. You can even try hammering it through some wood. Casing unlikely to get damaged through I've crashed into rocks and it lived
side to side i meant forward backward. As in away from the downtube and back
time to invest in a rubber mallet
Whacking the BBs out aint recomended
best option to salvage motor is to cut out the frame if heat/penetrants dont help
The case is made outta a shitty cast, wont hold up been tapped/Whacked out
^^ the results of heat/Penetrants and whacking
Was gonna cut out untill i realised motor case was fucked
How old is the cable and how. Much use has it seen
Cables stretch over time.
Only around 250mi. And yeah I know they stretch, this one's just stretching a lot faster than I expected.
There might be a defect if you say it keeps stretching, ie you reajusted several times already
If you have the time you can try swapping it. It's relatively inexpensive and if you don't have embedded routing a fast swap as well
except the bbshd isnt threaded into the BB it sides through
so penetrating oil and a rubber mallet on axle should get it out
eh, My bbs02 just slid in n out
Only threads were for the lock ring
exactly
which is why hes probably got it stuck because bb had some surface material internally
Isnt it stuck because of galvanic corrosion and dirt
that aswell but some BBs have some excess material and require some force to slide in the mid drive
or some filing
I filed the fuck outta my carrera orginally, fker still got stuck
Threads werent even touching frame
I thought that too with mine but it just took the right angle for it to slide in smoothly. Its a tight fit to angle it right
I'm debating this or just switching to hydraulic, but yeah. *something* isn't wrong, just not sure what yet. I should probably also mark the cable so I can confirm it's actually stretching.
Hydros shit all over mech brakes
ANYDAY
Mech to hydros is a no brainer
You don't even need to get "good" hydros for them to be better than any mech brake.
You can do what I did and get something in decent shape used (mine came from e-bay but there was used stuff on craigslist and FB marketplace) to use until you can get something really nice.
It was great. I swapped the front first and road it a bit to make sure it was working well. Then did the rear but was careful starting out 'cause my front brake was the only one I had confidence in but it was smooth as butter.
I guess my issue is that I've never had stopping power issues with my mech brakes, even with a cargo load. So the added maintenance and complexity of hydros seems like a general downgrade.
Mech brakes have like two moving parts :Shrug:
But I'll probably go that route if the cable is indeed failing.
What's the failure rate of hydraulic disc brakes? I am worried it may leak.
hydros are low maintenance. Self adjusting. Less work for that alone
you can buy prefilled, prebled hydros
Let
Let's not
@Heloc
lol
There are a lot of kids in this server
Because it does a poor job of explaining the concept or because it skeeves you out? üòÅ
No, because this is a PG-13 server
I was a kid once too you know. I know what goes on in those brains.
Wow, I'm trying to figure out how that comments relates to brakes, but I can't figure it out.
Bro didn't even sneak it into a conversation of nuts/bolts. Just came💦 out of nowhere
is there a deleted message here? wut lol
I don't have a problem explaining it to you.
It's all normal human shit. It's only weird if you make it weird.
I'm not sure how I made it weird
Then it's not weird!
But some people aren't as worldly as you and I.
||Mechanical brakes are like jerkin' off. It works fine and gets the job done but you're REALLY missing out by not going after the...upgraded version.||
With pre-made hydro disc. You just have to install it. I have like 3.2k km on mine on factory bleed.
What brakes do you have already
its not exactly a hard concept to understand lol
^^
How to upgrade brakes: Do you have mechanical? Get hydro. Do you have single piston hydro? Get dual piston hydro.
Got dual piston hydro? Consider a bigger rotor and adapter.
Have a 220 already? Get motorcycle brakes üòè
yea cause the 255mm stopsigns don't work
I've never even seen such a thing. I think my ktm oversized rotor was a whopping 270mm but the normal one was like a 240-something?
255 on bicycle seems hilarious
rofl.
lols at that adapter
PS: Those brakes pulse like hell, as @NCC1941 can confirm üòõ
Yep lol
They're so large that the 'stop sign' shape actually notably changes the contact area with the pad multiple times per rotation, from almost bottomed out in the caliper all the way to barely touching.
Does not make for a great braking experience.
Psttt, thats just built in ABS! /s
anti-braking system.
lol
Why yes, I did pair a 255mm rotor with a mech caliper like an insane person.
In my defense, they try to sell you on a much shittier mech caliper when you buy that rotor. lol
I do wonder if the caliper they try to sell you has super tall pads to mitigate the stop sign issue. Didn't buy it to test though.
It's not as bad as it looks
maybe it's designed for some specific brake caliper?
Interesting.
Certainly felt worse than that image would indicate in my usage. lol
Not that I'm disputing your assessment. Just raises more questions.
Tried to find the website to see the caliper they were selling with it, but it looks like they went out of business
All I remember is that it was a single-piston mech caliper with a "smash some letters together" brand name for like $30.
Found the kit and the caliper on Wayback
