Brake upgrade question

Hey guys, Since im getting back into cycling I wanted to ask another question about a potential upgrade item that i have never been a fan of on my bike.

Ok here goes, On my bike I have tektro quartz brake calipers. They seem ok dual pivot and what not. But one thing ive never liked is the lack of power. I already put some kool stop salmon pads on and that helped alot but i test road a felt z4? a while back, I think. 105 group set all around unlike my bike where they cheeped out on brakes and front der and tried to say it was a "105 equipped bike"

off what a difference. I wanted to make sure that it wasnt something i was missing. I looked down 105 brakes with stock pads and holders on the same cxp22 wheels as I had. but it stopped so much better. So it makes me beg the question. are tektro brakes garbage? do they have so much flex in them they cant adequately transfer braking force to the wheel?

So I wanted to ask your guys oppinion because my bike stops better but not as well as i wanted. I checked all the cables and everything to make sure i wasnt missing anything. they are all clear and smooth.

If brakes do matter what would be a good upgrade option? I was looking at 105 or Sram apex. I would like to keep it somewhere in that range but Im open to suggestions.
Also if anyone can think of anything im missing to help gain some of my "missing" brake force that would be great.

Thanks very much
Sean

I had Tektro brakes on my mid 90's mountain bike and felt the same way about the braking power. I swapped them out with some Avid Shorty 4's.
My road bike has the Ultegra brakes, which are great (not that I have much experience on anything else to compare it to) but being that your price range is in the 105 category, the 105's with decent pads or the Avid Shortys might be the right option for you.

yes OEM tekros are garbage....you can hide the problem a bit w/ new pads but they are still flexy and show up on long or demanding stops.

I've read allot of good reviews on these and will get some when I have the extra cash http://www.planet-x-usa.com/product-p/bcpxulcnc.htm

I've got Tekros on my Specialized bike and they are ok. I've been able to slow my bike from high speed on extremely steep roads without issue. For me, they would probably be the last thing to get upgraded.

Ok guys thanks for all the replys. So I just found out new 105 leavers are out of the question as they have the new updated cable pull instead of the traditional cable pull of my 2007 105 brakes.

So If I did want to upgrade my brakes I am not thinking about either sram force (dual pivot) easyer to set up with traditonal QR Hard to find reviews on them but they seem really nice and are about 150 on amazon.

Also thinking about those planet x brakes and have been reading up plenty on them, They seem really nice and have mixed reviews some say they are amazing once setup properly, I have also read that some of them are coming with ashima pads instead of swiss stop and as soon as you swap them out for swiss stop they work great.

I was wondering if any fellow clydes could chime in and give me a recomendation? Will I notice any increased power while swapping over to either of these brakes? My current brake setup is the tektro quarts and I have kool stop dura 2 in them and they seem much better than before but still not as nice as I was hoping.

Thanks again
Sean Scott

I have Tektro R559 dual pivots on my World Tourist, and it will stop as quickly as any other bike - even with me on it.

Get the 105's. I had Tektro brakes on my Specialized Allez and felt the braking was sub par. At the time I was 250 lbs at 6'3". I swapped for a pair of 105 brakes with stock pads and the braking power and modulation/feel was very noticeably better. I got a pair of new 105 brakes off eBay for $60.

By chance I just did a Tekro-ectomy on my bike to Shimano 105's. I got the 105's off of ebay for a little under $50 shipped (believe it or not!). They're slightly used and came off of a 2011 Felt F5 Team Edition bike.

It's not so much that Tekro sucks or that they flex. The problem is that depending on the model you have, they don't give you much mechanical advantage. Comparing my old circa 2005 Tektro brakes to the circa 2011 Shimano 105's, it's easy to see the design differences between the two, and how Shimano moved the fulcrum point to give you more clamping power.

Last year I had to replace my shifters since the right one failed. The bike came with the older Tiagra 9x3 shifters that were Flightdeck compatible, but when I went to replace them, the highest grade I could get was again Tiagra's, but they weren't Flightdeck compatible though. (They're 2011 ST-4500's BTW).

I was never thrilled with the Tektro brakes and after replacing the shifters the brake response got worse (probably because of the cable pull change). I know that has to do with how Shimano redesigned the shifters, but the Tektro brake calipers weren't anything to write home about before either.

Even with the stock pads on the 105 the difference between them and the Tektro is just nuts. It took me a day or so to stop locking up the rear wheel because i was so used to applying a death grip before with my Tektro calipers. Still with the stock pads it's amazing just how much of a difference there is (to me) between the two. I can come to a complete stop from the top of the lever hoods and hold the bike stationary on a hill whereas before I had to clench the brakes tightly from the drops to keep the bike from rolling.

Will *you* feel a difference? It depends really. With older shifters you will either notice that the brakes may be super-touchy or they may feel like mush. Personally I think it'll lean more towards super-touchy and that you'll have to adjust the brakes so that you have more control over them.

Even after replacing the brakes there is still a little bit of spongy-ness in the rear brake. That has more to do with the brake cable (the extra length compared to the front brake). Other than switching to a hydraulic system there really isn't any way to prevent that though.

BTW, keep in mind that you can just replace the rear caliper instead of doing a full swap. I got really lucky in that I got my 105's relatively cheap for a set, but you can get single calipers relatively cheap on ebay (new ones too).

BTW I did a quick look and it seems like the Tektro Quartz brakes are almost identical to the ones I had that came standard on my bike. Their newer calipers are using a new mechanical ratio, and from looking at the calipers they look very close to the 105's in design (the pivot points).

mine are really similar to that crash n carry only mine dont have that extra supporting member on the cable side. and the arms have a ton of flex in them. im still holding off. im gona do some upgrading/ repair work on my bike this winter because the two years I was off the bike I gained to much weight so I gota get back on it. Brake calipers arent on my "I GOTA HAVE IT" list but ive deffinately been wanting more responsive and more brake modulation. switching to kool stops helped a ton. but still not as buttery smooth and powerfull as that felt I tried a while back.

my bike had just as much power as the felt, but nowhere near the modulation and feeling as the brakes it had. As for now if i upgrade my calipers im still leaning towards the planet- X cnc I like them alot more than the forged, Im a techno nerd/ geek and I gota have the cool flashy stuff. I dont think the forged calipers are bearing supported on the main bolt. I could give a care less about titanium. work with the crap all day long and it has terrible corrosion.


Thanks everyone
Sean

My brakes weren't very high on my "gotta have it" list either. After I did it I wish I had done it sooner though!

I almost went for the Planet-X calipers myself. Only reason I didn't was because I got such an awesome deal for the 105's.
