Meezo Posted April 17, 2017 Posted April 17, 2017 Looking at the Guides....any one had issues with the lever not returning back fully when hot?Didn't you just get a reign, the deore on there pretty good! Rode a mates 2016 Camber, actually liked the deore's on there
capediver Posted April 17, 2017 Posted April 17, 2017 Didn't you just get a reign, the deore on there pretty good! Rode a mates 2016 Camber, actually liked the deore's on thereYip, new Reign came with Shimano Deore BR M615, with 200mm disc upfront...they solid but have not much fine feel and modulation...ON or OFF, not much in between...I'm sure they good but I have a trip to France looming and am worried about overheating...I believe you can use the ICETECH pad set up but will that be enough. These pads damn expensive and if the weather is anything like 2014, then for the price of all the pads you go through in two weeks, you could buy a new set of Guides! Last two seasons, I had Trails aboard and they were fine although did start to get hard on long descents....
MarcL Posted April 17, 2017 Posted April 17, 2017 This isn't really the tired old debate about which brake is better. I'm trying to get an idea of whether the overheating issue with the Guide RS is something to still be wary of. From my internet research, I get a lot of people praising the Guide RS as a phenomenal brakeset. But I've also found long threads (even on bikehub) about the brake's internals having to be fixed or simply being replaced by SRAM with no questions asked. So does anyone know if this is still a big issue worth considering? Would the SLX be more reliable? Thanks! Hi,I'm a big guy at 95kg.My bike had XTR 9000 (with Freezer rotor etc) and over heated on long downhills... Even with 180 rear rotor.Changed to Guide brakes and never looked. Very happy. I'm told its something to do with the oil. Shimano oil not as good as SRAM oil. Not sure why, but for me the proof is in the breaking. Maybe those "problems" were from version one brakes?Mine are perfect and over a year old now (including a Epic) Hope that helps.

Thanks Marc, that does really help. The Internet is a blessing and a curse. Researching potential bike parts is a bit like looking up physical symptoms. Before you know it your headache is actually a brain tumor and you have approximately 24 hours to live. Very simple things get over complicated.
Steven Knoetze (sk27) Posted April 17, 2017 Posted April 17, 2017 Had SLX for 3 years now and not one issue,been bled 3 times due to changing frames and it's been fine.The Guide RS should not be compared to the Slx but The XT brakes,if you want to compare SLX then it should be to the Guide RThe XT and SLX are basically the same brakeset. The XT has adjustment for lever reach and the brake pad pin is threaded as opposed to just a splitpin jobbie. Internals are identical, same performance. I have Guides, best modulation I have felt before. No issues with mine either but havent had them too long.

This is a dot 3+ Race brake fluid - not compatible with mineral oil systems, and NOT cheap - but doesn't give high temp issues anywhere near regular brake fluid. I used to bleed my race car brakes before every track outing (complete bleed using race fuids ) then swapped to SRF... now bleed once a year...

T-Bob Posted April 17, 2017 Posted April 17, 2017 Hold on, so are the new SLX an issue? I was about to upgrade to the new SLX groupo with brakes. I've got the previous SLX set and they have been across 3 different bikes and been faultless. Think I've only bled them once in 3 years or so to be honest and they haven't missed a beat.

Good question. Also wondered about the M7000. From what I read there was an issue with the XT M8000, which was then fixed by the time M7000 SLX was released. Something like that. Still interested if anyone has something to add on that.
V12man Posted April 17, 2017 Posted April 17, 2017 no issues with rubber o-rings and seals?I have never had an issue - 3+ and 4 have similar compatibility
Mada3400 Posted April 17, 2017 Posted April 17, 2017 I've owned SLXs, DB5s and i currently have guide RS's I got the SLX brakes new and out the box they had a very inconsistent bite point, which never went away and ate into my confidence with the brakes. They also didn't have that much power (200mm rotor, 26in wheel), if I leant back and pulled the front brake as hard as i could on tar the rear wheel would stay on the ground, so i sold them and got... Sram DB5s, also new, out the box these immediately felt much better, the bite point was consistent and the top end power was perceptibly more than the SLXs. "This is more like it" I thought, they were as good as the magnificent (albeit temperamental) Avid X0 brakes (thanks Cap) i had on a previous bike. With the DB5s I could do that brake into corners where your rear wheel has no weight on it, but is still on the ground, and even then i could feather the back brake so it wouldnt lock, seriously, they were that good. I later sold that bike, along with the brakes and got a bike with... The Sram Guide RS brakes, now these are much the same as the DB5s, only with more bite at the top end, which is fine because the modulation is there. Since getting these brakes I can now do pretty comfortable rolling stoppies, but I hesitate to put that down to only the brakes as the whole bike has changed. From my experience, the Guides are pretty magical, I hear they have had a pretty patchy reliability history, but spares should be quickly available, I would say the sacrifice is worth it. If you're on a budget however, the DB5s I had blew the SLX brakes out the water.
Skylark Posted April 17, 2017 Posted April 17, 2017 The deore 615 is the best value, basically Xt/slx but without all the adjustment knobs or bling, pretty awesome brakes. The shimano lever is amazing and the modulation/power is good.
