Hi, I faced the same issue 2 days back when i was on a ride to chikmaglur in my apache 160 4v. I was on a steep downhill with pillion partner riding from chikmaglur to kemmangundi, the road is full of red dust, potholes and gravels, I was pressing the rear brake pedal too hard to have control over the vehicle. And suddenly I sensed that the rear brake is not responding at all. However the front disc was working fine. I came down hill, stopped the vehicle and touched the disc. It was super heated. I waited for a while to cool off the bike and then i realized the brake was back in action. I continued the rest of the ride without any issue. I had faced a similar issue when I was riding downhill in BR hills in october 2020. I stopped for a while allowed the vehicle to cool off and then the brake started working again. I consulted some experienced riders and came to know that this is a common issue when rear brake is overused because of which the pressure fades away.This is known as brake fading. We need to use front brake more than the rear brake along with engine braking and gear downshifts more to avoid such issues. Happy riding!

I am suffering from the same problem. I have changed master cylinder twice and now the thing… diskpads got too hot to stick up with disk and jammed the rear tyre… after cooling it down it gets normal….. but the issue is an issue…..either with royal enfield or with any other bike..

I faced the same issue. But it happened for me during normal traffic. Brake completely faded away. Zero pressure on the pedal. Thought it was the fluid but seems the culprit is overheating of the rear disc.

thank you brother 🌺🌺🌺🌺🌺

apply water to cool down.. very common on hilly areas

You should be using mostly the front brake and the engine for regulating your downhill speed. If you were only using the rear then it will get hot and fade. I hardly ever use the back brakes. 17,000 miles of hard use and I still have the original brake pads front and rear. The rear brake also locks up very easily and will put you into a skid. I don't think I have ever locked up the fronts on the pavement. Even in the dirt, the front brake works great and it takes a lot to lock them up.

This happens very often here in Darjeeling where there are continuous downhill.. specially if u are doing double ride its very common issue.

That's because most of people have habit to keep feet on break leaver. If not required one should not keep their feet on leavers. I almost went downhill at Khardungla pass.

This makes me wonder, should I really go for the Himalayan BS6 or the Dominar 400. What's your suggestion?

I too facing same problem once bro.. after cooling down of disk that will come to normal

Same bike same problem, but in 2023. If you leave them for 5 minutes breaks will cool and everything gonna be alright

Exactly the same thing happened to me during my leh trip recently, this happens only with Himalayan... bike is shit, we need to raise such defect with Royal Enfield company...

Even I am facing the same damn problem with mh himalayan, changed 3 rear brake cylinders but no use. Bloody non reliable vehicle brother . Don't buy the himalayan if you value your life. I am.not new to re, I own old model re as well, no issues with that.

Pour 1 ltr water on disc for immediate fixing :)

I'm also facing the same....I changed the braked fluid...still facing the same issue....I guess as u said it might be because of heating up of brake fluid....please share if u have resolved ur issue after changing the fluid.... Also share if there are any other solution....using better fluid ... Thanks in advance bro....

It happened to mee too it was because the back breakpad has worn off...

Once u own a royal Enfield u become a mechanic.

Same thing hpd in my friend duke250 in Kodaikanal .

🥺🥺

Whenever you face such issues of braking then put water on rear disc and continue riding, temporary solution. Common issue with RE.

I should be careful then 😜😜😜

This bike has a million problems. Fed up with that, now i wish I could sale

If it has happened for the 2nd time then It's not the bike's problem. Learn to do engine braking and don't keep hanging on to your brakes while riding downhill. And this happens with any bike if you ride it like this.

I faced the same issue thrice in a day on my himalayan

I face the same problem it happens to all bike it's because of too much heat you should pour some water on disc brake

There is no blockage and nothing wrong with the rear caliper or the brake line. The guys at the service center will not be able to do anything. Stop riding the rear brake pedal while riding downhill and use both the front and the rear brakes in tandem, while trying to slow down or stop. Problem solved. Also when was the last time you replaced the brake fluid ??? Brake fluid has a sort of running hour life, explained in layman's terms. Since the technicalities will confuse you, as you are not familiar with motorcycles or their parts, as you do not know the difference between a master cylinder 3:48 and a brake drum.
