Martyn_T Posted March 22, 2015 Share Posted March 22, 2015 Morning all, I've just ordered some new brake pads for my Maverick Blackout XB because I have noticed recently it has been taking longer and longer to come to a stop when attempting to brake. (When it was new it could stop within about 4 metres from top speed on grass - you really could rely on them). Now they don't seem to do anything but hold it at a standstill when it is stopped, if that makes sense (for example it would hold on a hill or something). As I am still new to all this - is there anything I can do to inspect the brakes to check if they are still serviceable? Or do I just accept that as they are not effective, that they need replacement? Finally, if anyone has any online guides on how to do this then please point me in the right direction because they do look like I need to take half the car apart to replace the disks. Cheers for any thoughts. Martyn. Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted March 22, 2015 Share Posted March 22, 2015 Not 100% on the Blackout brake setup, but mostg setups have some form of friction material...and that will wear out. Can also be good to strip and clean every now and again. Just don't use anything that leaves a resudue when you clean the discs Quote Link to comment Share on other sites More sharing options...
Martyn_T Posted March 22, 2015 Author Share Posted March 22, 2015 (edited) Cheers Nitro - I'll take your advice on board when I start the strip down. There are two ? ceramic disks which are placed in contact with three angled metal plates when brakes are applied through the servo.

Nitroholic Posted March 22, 2015 Share Posted March 22, 2015 I've had cars with composite discs...and they can get contaminated with dirt and grease, and there isn't a lot you can do to clean them. Brake cleaner and an old toothbrush really. 1 Quote Link to comment Share on other sites More sharing options...
Ian w Posted March 22, 2015 Share Posted March 22, 2015 You are going to have to take the gears and clutch bell of like this then you should be able to get at the brakes. If you have ordered the parts I would just replace them. Just another thought before you teat it to bits has the radio system you are running it on got End Point Adjustment if so see if you can expand the EPA that may help. If it`s the original radio systen then it will not have EPA. Hope that helps 1 Quote Link to comment Share on other sites More sharing options...
Martyn_T Posted March 23, 2015 Author Share Posted March 23, 2015 Ian W and Nitro, Thanks both for the help... the image is really helpful and saved me actually emailing HPI to ask if they had any info sheets on replacing the discs. I have got a FlySky FS-GT3C Transmitter but I think I have gone as far as it will go with the end point. I suspect rather than the disks being worn down they are fouled with grease or oil (there have been a few problems with the expansion chamber coming loose and all sorts of exhaust stuff being fired all over the vehicle. I did clean it up as best I could before refitting (with thread lock this time, LOL) but I wasn't able to easily reach the brake disks. That pic is really helpful though. I am new to all this (only been doing this 12 months) so I don't know if this is something most people would already know... but it is a shame the forum doesn't have a repository of images like this that people can refer to. I did do a google search on a strip-down of a XB but there was nothing - just a load of youtube vids of people driving them. Anyway - once again, thanks for the help and advice... it has set me off in the right direction. Martyn. 1 Quote Link to comment Share on other sites More sharing options...
