AJ9604 Posted December 17, 2010 Report Share Posted December 17, 2010 what are peoples experiences of running a booster on the inspired fourplay as it flexes on the rear, i'm running tnn lgm pads on hs33 2005 with 4 finger lever, bled with phat phluid. I feel the pads hit the rim and its all good until i pull harder and the frame flexes and i can pull the lever an extra cm or more. so i was wondering if i put a booster on i know it will stiffen it up a bit but will it affect my braking? Any help would be great. AJ Quote Link to comment Share on other sites More sharing options...
ogre Posted December 17, 2010 Report Share Posted December 17, 2010 it will stiffen up your brake, but with some pads this isn't the ideal situation as some give is needed for the pads to twist into the rim, or whatever, i just remember krisboats rambling about his t-rex with cousts on the back going from good to bad when he ran a booster. if the flex worries you stick a booster on there, no harm in my opinion, i run a built in booster and a booster on top of my brakes too...

chris4stars Posted December 17, 2010 Report Share Posted December 17, 2010 on the back of my fourplay i ran with tnn belays, cnc backings with a light grind on trialtech rims.... the addition of the tensile fourplay improved the braking for me no end! it was far too flexy beforehand, id recommend it to anyone Quote Link to comment Share on other sites More sharing options...
Sam T Posted December 17, 2010 Report Share Posted December 17, 2010 Running a booster will give the lever a more solid feel, and also put more power into your rim rather than flexing outwards. If your worried, just get a 2 bolt. It will elliminate most of the flex, but not as much as a four bolt. See Here Quote Link to comment Share on other sites More sharing options...

rupintart Posted December 17, 2010 Report Share Posted December 17, 2010 I don't understand why you WOULDN'T put a booster on. Boosters do three things, they protect your rear brake from your foot hitting the crossover and/or lines, enhance brake performance, but they also improve frame/mount life. The frame life pertains mostly with V-Brakes because the surface area isn't as spread out as it is with maggie mounts, but frame life none the less. If you're seeing the frame flex outwards, get a booster. The coust pads working like crap after adding a booster is garbage. I ran coust pads (both "variants" for you people who still believe the michael coust ones are different than the heatsinks) before and after a booster and can tell you my brakes got marginally better with a booster. That person probably didn't know how to set-up his brakes. Actually, every set of pads I've ever ran have been with and without boosters (Monty milk, koxx bloxx, koxx browns, Plaz CRMs, CRVs, coustsinks, and "real" cousts, and probably some others I can't remember) and every time, with a booster has been a massive improvement. Mind you, almost all of those pads are on both V and maggie set-ups. Get a booster. 1 Quote Link to comment Share on other sites More sharing options...

I used to run a booster on the Inspired but then, when I put the Phatpads on, I found that I actually preferred to have a bit more 'feel' (flex) in the lever and so took it off. Saved a bit of weight and cleaned up the look of the brake area too. Quote Link to comment Share on other sites More sharing options...

Saved a bit of weight and cleaned up the look of the brake area too. Yeah, I agree on the point that having a bit of flex at the lever is nice. I have found that a stiff booster has a much bigger effect on brake performance than metal backed pads though... so I've gone back to plastic backed pads. My frame already has an in built booster, but with a heatsink booster added the brake hold went up quite noticeably! Coupled with some koxx pads this has made for a pretty awesome set up Quote Link to comment Share on other sites More sharing options...
AJ9604 Posted December 18, 2010 Author Report Share Posted December 18, 2010 Cheers for all the replies guys, I will try a booster on there to see how it goes but by the sounds of it will improve my braking and reduce the flex which will be good.

Topsy Posted December 19, 2010 Report Share Posted December 19, 2010 You just have to know that you can't put all boostern on the bike. If you want one that matches the colour I'd go for the 2bolt echo sl and then drill 1.8mm (think it was 1.8 by me...) out on each side. ^^ Helped a lot by me.

rupintart Posted December 19, 2010 Report Share Posted December 19, 2010 alu backing are more of a durability reason than feel. Whilst the feel is a byproduct, the alu backing won't split or break on you like plastic will. Most all of the brake backing issues have been solved by an alu backing.

Pretty sure that the majority of people buy and use CNC backings so they only have to buy cheaper material inserts, saving money in the long run and for the benefit of a stiffer more positive feel at the lever. But as has been said, if the frame is visibly flexing then try a booster. Quote Link to comment Share on other sites More sharing options...

But if he's not breaking them, then no reason to upgrade I guess... Quote Link to comment Share on other sites More sharing options...
