Rear Brake Master Cylinder Caliper Assembly Replacement for for 50cc 70cc 90cc 110cc 125cc Chinese ATV Quad Taotao Boulder B1 Coolster 3050HD

There will be a few changes to make! This is supposed to be the rear bumper for my son's There is the same bolt spacing between the caliper brackets, but there is a different back spacing. As a result, you will need to place 'shims' (I used washers) at the end of the mounting bracket and the brake caliper piston, so that the piston can apply enough clamping force. Approximately 1/4'' worth of shims was necessary in my case. The caliper needs to be installed, and you'll need to manually pump the master cylinder until brake pads make contact with the rotors. If you want to use your brake lever, you'll need to adjust or even modify clevis mount on the master (I had to take out some bolts on the master). Summary If I had to sum it up, I would say In comparison to the $80+ I'm seeing for the technically correct part, I'd much rather put the effort into making this work than the $80+ that I see for the part from my local dealer or online parts provider. However, in spite of the fact that the part needed work, the original description was vague (says However, a different model) led to some uncertainty, which is why I gave 3 stars. Despite the differences between the two, I'd still purchase it again. Purchasing a brake caliper for 10% of the cost of the machine.

According to the description, it works with any atv, 90 cc or larger I 111- The 125cc engine. The linkage didn't fit my bike. I ended up using some of the old parts linkage to make it fit. After installing it, the rear disk brake would not depress properly, the brake pad kept getting wedged under the disc. After watching a few youtube videos, I found out that I needed to shim the caliper if I wanted to make it work. You can purchase one of these, they are good, but make sure you pay attention to the master cylinder linkage and compare it to the one you currently have. If they are different, it is not the right part for you, so you might want to get the other one, which The pictures look similar enough to overlook the critical parts (be careful when ordering since they and the items look the same).

Compared to the one that came with it, it is much A few people have contacted Amazon about being late, and most have been told to just wait! It's not clear to me why I have to pay for prime!.

Other reviews refer to this not fitting their Coolster ATV 125cc 3125R as a problem, but I found it fit my ATV almost too tightly. After changing it out and installing the new brakes, it took me about 20 minutes.

There are a lot of advantages to this product for the price however, they should put this information in the description and/or have a video on how to install it. It is just as good as or better than OEM on both the brake caliper and the.

I was unable to bleed off the brakes and engage them. In this case, they would not act. In case the other set fails, I will keep them for spare parts.

I bought it for 125 dollars in 2009. In order to mount the cylinder, a hole had to be drilled out on the top mounting end because the cylinder wasn't sitting evenly with the bottom adjustable slot. In my opinion, the brake line had to be bent at the top of the cylinder due to the ease of shipping. It was bent straight down by the shipping box. To bend it carefully, I had to clamp it in a vise. I was able to get it to work, as expected.
