Re: Ruined $150 Shimano Deore hydraulic brakes

One thing is clear. Brakes need to have standard, published metric's. Heat- temp limits, energy dissipation /time and or possibly duty cycle are a few I would like to know before specifying them for a tubby on a high power e-bike. We are all just pissing in the wind without them. Plastic piston sea...

Re: Ruined $150 Shimano Deore hydraulic brakes

I have the really good Shimano metal sintered pads for saint and zee. They last about 1000 miles under current conditions. I burn through em once a month.

Re: Ruined $150 Shimano Deore hydraulic brakes

What about dual brakes? One method is dual disc brakes, to help ease the heat buildup. Needs to have flanges on either side of the hub, more costly. Could do that front and rear. Also use quality disk pads from a known entity (bike store) not generic pads and not from an unknown source like most of...

Re: Is Portland ebike friendly?

You might look at New Mexico, where it rains a whole lot less, and you can build whatever e bike you want. No particular law at all, and cops are too busy with other shit. Stop at the stop signs and its all good here. Of course, you will have to work again sometime, so where you go may depend on wh...

And there is the problem.

All to often OP's are not clear and often vague and hardly clear it up or come back in some cases.

Is Portland ebike friendly?

I live in Los Angeles currently but am thinking about moving. I've been to Portland before and I like how the city is pretty clean and has so many trees and clean air. I know it rains a lot there, so I am wondering if any members live there or have any experience in the PCNW. I know ebikes don't do ...

Re: Confusion about which controller to buy for Voilamart 1000w hub motor

Plan to replace the plugs as necessary and work out the phase and Hall wire assignments yourself. After those things are taken care of, there's not much else to it unless the controller needs a display you don't have. There's a self learning wire. :lol: :lol: :twisted: I had that controller before....

Re: Ruined $150 Shimano Deore hydraulic brakes

-Use appropriate rotor sizes. There isn't a limit to rotor sizes on forks. You can have a crappy fork that is dangerous to begin with, which is likely because most ebikes come with some pretty shit forks, and a lot of teh forks I see used on this forum, I wouldn't touch with a 10' pole. however wit...

Its super difficult to get it to stop rubbing completely. Every time I change a flat, take out the wheel, it needs re adjustment

Re: Ruined $150 Shimano Deore hydraulic brakes

Can't say I agree at all with mechanical disk brakes. they are pretty crappy and every one of them except for pauls or trp spyre have a moving caliper piston only on one side and the other is fixed. It's an inferior design to be perfectly honest. BB7's were some of the better ones at the time (this...

Re: Ruined $150 Shimano Deore hydraulic brakes

Yes the pads were rubbing a bit, does that contribute to heat build up? My rotor is ever so slightly out of true. A car pulled out in front of me and I bent my front wheel in half to stop in time.

Try cleaning them out with some spray cleaner and a brush. Could be clogged with brake dust.
Just did this and can confirm it did NOT work. But I was able to verify that the fault is somewhere in the caliper. Either a manufacturer defect or my own fault.

Why not roll around with a bottle of water to cool the brakes, just have a rubber hose taped to the bicycle tube so it can drip water, after you brake turn the lever of water.
do you mean the caliper or the rotors?
