Brakes Noisy hydraulic brakes on Lectric 3.0

[Wireyouup]

I have a new Lectric 3.0 with hydraulic brakes, about 50 miles now. The rear brake squeals very loud, front is fine. So loud it is embarrassing around others so I don't always use it, could be dangerous.
Customer support says it takes 50 to 100 miles to break in, so far it is not getting any better. They say they have no other pads to offer.
Can anyone vouch for the company that this problem will go away? Do you know of a fix?
Otherwise I love the bike.

1st Step = adjust the Rear Caliper & Pad Alignment- 5mm hex - no torque wrench required just don't over wrench it

: CLICK HERE ADJUST REAR CALIPER & PADS

2nd Step = this guy has a level head most likely "contamination" which could have happened at the factory - with Rubbing Alcohol to clean that rotor (don't get fancy with harsher chemicals) - pc of 100 grit sand paper to lightlyt smooth the surface of the pads - you won't need to resurface the rotor : CLICK HERE LECTRIC 2.0 REAR BRAKE SQUEAL FIX

Thanks this helps immensely, I will give it a try Sunday.

Well I resurfaced, re-aligned, cleaned with rubbing alcohol. It is better but still squeals somewhat, suppose I'll give it more time.

Hey - Kudo's to you on the followthru - I mean that with respect. Ypu made a decent stab at it - got it a bit better - now you have a little more heart into your bike. Couple of days circle back to youtube - my experience I look for the "level headed guys". There is a "bedding procedure" for Hydraulic eBike Brakes" - several different procedures all claiming to be "the One".

Saw the video about a spray product called De-Squeak by CRC. Cleaned rotors and went on a break in ride it worked immediately, gone on several rides since, all good. Thanks for the tip!

Usually, brake bedding will solve the squeal problem. Especially on hydraulic brakes where they can't be adjusted (and don't need to be) like manual brakes where there are cable stretch and pad placement issues that creep in.

Riding in the rain will clean off the rotors so the layer of pad material that is bedding on is gone. They'll squeal like crazy until a new layer of pad material is bedded back on.

Also usually: Cleaning rotors is just a temporary fix without bedding.

Those videos above are meant for cabled/manual brakes, not hydraulics. That second video was horrifying. Pad glazing is addressed by the holes in the rotors and the pads skwunching up against and across them. Not sandpaper for God's sake. And the bedding procedure he shows includes a full stop which you should never, ever do. You always want to brake to a slowdown, not to a stop. Leave hot pads over one spot on a rotor, even for a moment, causes uneven rotor cooling and thats how you warp a rotor. Look at bedding instructions for both bicycles and cars and you should see pretty much all of them but this one telling you not to brake to a stop.

It’s important on Lectric e-bikes before 1st use to clean the oil/crud off the rotors before engaging the brakes for the 1st time or the pads will become contaminated and need to be replaced. I’ll post a picture of the gunk that came off the XP Trike rotors. Keep in mind that I used both sides of the paper towel so whatever gunk you see in the picture is mirrored on the reverse side.

I used a piece of paper towel sprayed with automotive brake cleaner. Keep in mind this is one rotor on a brand new Trike
