Martin Reynolds Posted August 3, 2012 Report Share Posted August 3, 2012 Removing the weaker 'right angle' bit from the '05 lever and using a stronger, more reliable TPA system are arguably improvements. Fun fact - had someone tell me on the phone two days ago that they felt Joe Maher's brakes (2011 Maguras) and they were surprised at how good they felt and how stiff they were. I've never had an issue with the older tpa's;Just keep it well greased, and don't wind it completely out! Quote Link to comment Share on other sites More sharing options...

craigjames Posted August 3, 2012 Report Share Posted August 3, 2012 Aye, the TPA on 05 maguras is poo, but a nice shiny metal one and you're sorted. 1 Quote Link to comment Share on other sites More sharing options...

N.Wood Posted August 3, 2012 Report Share Posted August 3, 2012 I've never had an issue with the older tpa's;Just keep it well greased, and don't wind it completely out! They still strip if you put enough pressure through it... Putting a plastic component in that application is pretty redic. My metal one has been going strong for probably 4 years now.

Jake. Posted August 3, 2012 Report Share Posted August 3, 2012 Oh I didn't realise magura made some weird metal lol, I find my brake a little bit spongey but far more powerful than the previous years. I've had a go on some good 05's but I prefer a good set up 2011. Quote Link to comment Share on other sites More sharing options...
Maxx Posted August 3, 2012 Author Report Share Posted August 3, 2012 So if I use a 2 finger blade it will feel almost like a 4 finger blade on a 05' hs33 ? I tried to press hard on the lever blade, and the body doesn't move (or maybe 0.05mm ...), so I trust Adam explication, I don't see others explanations. In terms of leverage ratio it will be : 2005 2 finger < 2005 4 finger ~= 2011 2 finger < 2011 4 finger ; right ? If yes it can explain also why even with a bad set up, my 11's hs33 hold well.

You could just set your brake up well, then it would feel better haha Quote Link to comment Share on other sites More sharing options...
Maxx Posted August 3, 2012 Author Report Share Posted August 3, 2012 I meant by "bad set up" that my grind is completly dead (cause the rim is nearly dead, so I try to reduce the frequence of grinds), so it won't change the lever's feeling. But I'm (just a little ... ) maniac with my bike, it can explain some things ... By the way is there anybody who have ever tried to run a hs33 with two brake boosters (on the same brake - rear or front) ? Quote Link to comment Share on other sites More sharing options...
Jake. Posted August 3, 2012 Report Share Posted August 3, 2012 By the way is there anybody who have ever tried to run a hs33 with two brake boosters (on the same brake - rear or front) ? That sounds utterly retarded why would anyone do that, one booster should be enough... 1 Quote Link to comment Share on other sites More sharing options...
Maxx Posted August 3, 2012 Author Report Share Posted August 3, 2012 Yes maybe, I've never used a brake booster, because for 8 years I have ridden bikes which have had built-in booster, but maybe soon I will get a frame without brake booster, so I would buy one and I was wondering if two brake boosters give a better feel/brake rather than 'only' one ... One under the brake clamps and one on the top. Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted August 3, 2012 Report Share Posted August 3, 2012 the only differences between bleeding old and new ones are to unscrew the hose port 2 threads and to pull the lever slowly,then let it go back qiuckly a few times. i dont think that is the biggest problem of the new ones. i also dont see a point in the need of more power,the old ones had way enough. more power=more frame flex=more spongy lever.plus composite....

You don't see the point in more power? Hmmm let me think about that one... So the brake holds and bites better? Isn't that what trials riders want? As for the frame flex, I've heard that can help give bite. some riders don't use boosters for that reason. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted August 3, 2012 Report Share Posted August 3, 2012 Just because the power is there doesn't mean you have to use all of it, all the time. Better brakes = less need for stupid grinds = less retarded noises. Quote Link to comment Share on other sites More sharing options...
Jake. Posted August 3, 2012 Report Share Posted August 3, 2012 Exactly luke. If I had a brake that would snap the frame apart if I squeezed it, that's TOO much power, anything that can be super super powerful (which means less effort in terms of squeezing the brake which leads to less fatigue during longer riding periods, I've often had to stop after a few hours due to not being able to hold the brake hard enough).

Luke Rainbird Posted August 3, 2012 Report Share Posted August 3, 2012 More power from the same effort generally = same power from less effort, resulting in less fatigue and all round win. Don't blame the brake, just squeeze less 1 Quote Link to comment Share on other sites More sharing options...
315r Posted August 3, 2012 Report Share Posted August 3, 2012 Yeah, but they're not made out of metal either. It's Magura's own composite material rather than one or the other... Composite, plastic. Anyway, is not aluminum or other pure metal. This is what i want to say. Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted August 4, 2012 Report Share Posted August 4, 2012 Composite, plastic. Anyway, is not aluminum or other pure metal. This is what i want to say. pure metals are crystal salts.just saying Quote Link to comment Share on other sites More sharing options...

LEON Posted August 4, 2012 Report Share Posted August 4, 2012 Bought a full brake, sold it a week later, it was perfectly bled, it was a new 2 finger HS33, and it was awful. The same as every other 2011 brake I've felt (Yes even Joe Maher's, they felt horrible to me) The 04 HS33 it replaced was solid, it had a proper firm biting point and it ended there, with the 2011 you can vaguely feel when the pads meet, followed by another load of sponge. If the new ones are "too powerful" then I'd like less power, I didn't hear any complaints from previous models. But I think the issue is more with what the lever is made from, it's just not good enough to please everyone on a trials bike. 1 Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted August 4, 2012 Report Share Posted August 4, 2012 (edited) one guy in the german trials forum is working @ magura,he said,he doesnt identify with the new products anymore and wants to bring out his own brake.he mentioned the composite-"scheiss" several times. now that is a statement. i think people who say old maggies are not powerfull enough are sitting at their computers all day long instead of riding and therefore dont have the strength in their fingers to brake. little joke...

Maxx Posted August 8, 2012 Author Report Share Posted August 8, 2012 I was ok with Adam's explication, but I just notice that the new lever blade is about 1cm shorter than the old lever blade (both 4 fingers). So Adam why did you say the ratio is higher ? Does the fact that piston is inline (and not radial like the old) influence this ? Quote Link to comment Share on other sites More sharing options...
