Which disc brakes?

[KillerCars]

Hi,

I am relatively new to biking so forgive me if I don’t understand a whole lot!

I have a Mongoose Tyax Elite 2009, and the brakes have always sucked on it (some Promax rubbish). Anyway, not more than a week after I got it the rear brake started squealing.. 6 months on it sounds terrible and they don’t stop me all that well anyway. I know from reading reviews about my bike that the brakes are pretty rubbish anyway so I’m looking at replacing them altogether with something different.

After browsing around I am interested in getting some Avid Juicy 5 or Juicy 7 disc brakes, but there are a few things I’m unsure about. Is my bike IS or Post mount? The standard rotors are 160mm but can I put something bigger on like 185mm? Any help and/or suggestions of what disc brakes to get would be much appreciated!

Cheers,

KC

hi bud. it wont make a difference what the brakes are aslong as when you buy your brakes you get the correct brake mount for the model. if you nip the old ones into your local bike shop they will tell you straight away and then you can hit the bay. as for the size rotors you can go for ive found a link for you to look at about the forks on your bike and it says maximum disc size is 185mm but just double check with the link below that these are your forks as bike companies change spec from time to time but bike radar gives this as your fork. i will try to find if yours are post mount or is mount and get back.

seems that your front brakes are post mount and on a forum i was reading a bike tech sugested that you stick with the 160 you have as these should be powerfull enough for this model. check ebay for brakes though. ive used hayes 9 and they are excellent. hayes stroker trail and they are awsome. juicy 3 and they are good. if on a budget try giant mph route as my mate had them and they work sweet and as a bonus shimano pads fit in them and are only £8 a set for the real thing. ive just brought a bike with xt brakes on them so will review later if anyone interested.

I looked at my bike and the forks I have are SR Suntour XCM V2’s… I looked these up and it says max disc is 185mm too, and they do look like what I would consider post mount like you said.

I’m not all that bothered about changing the front brakes so if you don’t think it’s necessary then that’s fine by me. I was just really interested in changing my rear brake. I guess if I find out what frame my bike has and look up the details on it I should be able to find out what mount type it is, etc.

Anybody have any comments on the Avid Juicy 7 disc brakes? I found them somewhere for 52% off on the 2009 Juicy 7 brake so I was tempted to buy it… Unless they’re rubbish?

hi bud, found some juicy 7 on the bay but big bucks. here is a link below for a saved seller of mine on the bay. ive brought loads from him and he sells quality gear honest. check out the hayes nine hes got with 203 rotors. that would see you right. hope you get sorted. if i find anything else will get back to you.

try these brakes aswell as ive had these and they are awsome and i was running 160/180/ these are 203 so should stop on a pin. they have all the juicy brakes on here aswell if you track back on the site a bit.

Thanks for your help – I’m having trouble finding out what mount type and what the max rotor size my frame can handle as I’m probably going to leave the front brake as it is. Do you know any way of finding out?

Thanks.

hi again bud. there are a couple of options for you. 1, take it to your local bike shop and they will tell you what mounts you need straight away. 2, check out this link above , it has a phone number you can call and ask any questions about your bike. id go to the bike shop as they may have some brake mounts and discs you can try out. 3, find a mate with some hydraulic brakes and mounts that match yours and have a play with them. even if you are not competent at bike mechanics they are only bolt on/ bolt off brakes if you remove the whole brake and calliper at the same time. just be careful not to press the brake when of the disc as hydraulic brakes can close up if the brake is pressed and then its a pain in the ass to get them back right. check out you tube on changing disc brakes as there are loads of videos to guide you. if you already know what to do sorry for going on like you know nothing. just trying to help.
