Hydraulic Disc Brakes Solved

[Deleted member 4366]

My new switched hydraulic brake came today and it works perfectly. Took about 2 minutes to fit and a bit longer to wire the switch to the controller. It's a simple normally off switch the same as non-hydraulic switched levers. This is an excellent solution to upgrade your front brake on any e-bike for approx £60.

What's the advantage of an hydraulic disc brake compared to a standard one?

And I suppose if I have brake pad, the upgrade won't be possible?

Modulation, they are more powerful and don't need adjusting.

Cons, slightly more weight, not as simple to fix should you snag a line or pipe. More expensive.

 

[cwah]

Why do you mean by "they don't need adjusting"? I suppose the disc would still bend from time to time or rub against the caliper. Then you still have to adjust it?

Bicycle hydraulic brakes are self adjusting, the same as with cars. As wear of the pads takes place they take up the slack to the new position by drawing more fluid from the reservoir. A bent disc just has to be straightened or replaced.

 

[JuicyBike]

All the force is transferred through the hydraulic fluid, from your fingers to the pad surface, whilst with cables there is a great deal of friction and stretch which wastes some of the effort applied at the handle.

Hydra brakes are just better. But It always seems like over kill unless your doing some really aggressive downhilling. The brakes do get hot on an ebike as the disks are so thin but your applying a different set of rules with an electric bike as you can speed up much quicker and often that you would un-powered.

My mechanicals seem to do a fair job of tipping me over when adjusted well. They start to fade from that moment as the pads wears though. I can see the appeal in the hydra ones and not adjusting.

But then you'd have to make sure they where always bled correctly and made sure the pistons / seals are in good shape.

Ok thanks. Doesn't solve my problem with the disc always bent on the wrong position. Somehow I think for bike it's maybe an overkill as scottyf said.

This is great to know we now have the option to fit hydraulic brakes with e-braking, Thanks for bringing to the table......

cwah, Justed fitted new calipars and 180mm disks today, the rear disk was bending/flexing on application, easily fixed with loosening the fixings on the top of the calipar and squaring up with the back pad, then nipping back up... There are sooo many adjustments on calipars not all are obvious, have a play

 

[cwah]

Yeah, I usually have a play but everytime I adjust on I side it make it bent on the other. Really long and difficult to adjust correctly the disc.

 

[Scottyf]

I never found disk brakes that difficult to adjust. Maybe becasue its all pretty standard fit.
Just move the stationary pad as close to the disc as possible without it touching.
Then move the floating pad to a decent bite point.

Then fine tune at the top of the handle bar adjuster.

Seemed quite intruative.
