Shimano 105 poor wet weather braking

Postby dantheman1979 » Mon Nov 26, 2012 22:59 pm

The 105 brakes on my CAAD 10 are awesome in the dry but in the wet they are downright scary. Can anyone recommend some different brake pads that will improve wet weather braking? I am currently still using the stock ones that came with the bike.

SwissStop Greens, around £20 from CRC IIRC.

+1 for greens , but koolstop salmons get as many good reviews.

Any brake pads work if you know the correct braking technique in the wet. Sure Koolstop Salmons and their like might be a bit better, but you should be fine with any pads. When the rims are really wet (e.g. from standing water) are you braking for a couple of seconds, then releasing briefly, then braking again? And are you routinely feathering the brakes to clear water?
More problems but still living....

There's squat between any pads in the wet and as previously mentioned you have to adjust your braking in the wet. But for arguments sake.....Probably the worst pads i've had though are the salmons, overrated isn't the word and in the end i swapped them for a set of BBBs i had lying around the shed, these out performed the salmons.
I use the Shimano pads that come with the caliper, when they need replacing its Swissstop green and both are fine.

Not true. You've obviously never tried to stop in the wet with Tektro pads. Tektro pads are dangerously ineffective in the wet, even on my new Ambrosio Excellight rims (same goes for other rims with the same pads by the way), and they pick up and retain aluminium swarf from the rims in the pad surface creating a very effective grinding medium with the road grime.

Swissstop greens are like night and day in comparison - effective stopping and no more grinding - using the same good braking techniques you describe.

Another vote for Swisstop greens :)

Transformed my crappy tektro brakes on my hack, dry or wet :D

I am aware of the need to clear water from the rims but it makes no difference in this instance. I think i'll give the swissstops a go and see how i get on.

Err there's a big difference in performance between decent pads designed for wet weather use like koolstop salmons/swisstop greens and generic cheapy pads. Shimano's OEM pads are fairly decent these days but were very poor going back 3 or 4 years. Sure there are techniques everyone should be aware of to improve your wet weather braking but pad compound still makes a very noticeable difference

I dunno if it is just me, but I have koolstop salmons on my 105 brakes. In the wet, I really need to grip it pretty hard from the drops for 1~2 seconds before getting any proper brake action. Otherwise they are still downright scary. Not sure if this is the case with all pads in the wet!

I found almost found out the painful way about Tektro brake pads.. nearly ran into the back of a stationary van at 20mph :oops:

Not sure I agree with that. I've got tektro pads on my bike (the cartridge ones) and I can stop ok in the wet. I can even lock the rear wheel no problem.
Also I had the blocks off at the weekend and there can't have been more than one or two metal flakes stuck in the friction material.

That said there is a bit of technique involved. You can't just pull the lever and expect to stop like you can in the dry. I do find it helps to keep the rims clean though, I give mine a rub over with a rag and white spirit which keeps the surface good for braking.

Aztec pads are pretty good. However I'll stop the bike with almost any pad so long the brakes are properly set up.

what are you wanting to brake for anyway, it will only slow down.

My tektros have been fine in the wet.

I really was badly surprised how poor my new 105 brake pads are in wet conditions, indeed! Need to find better alternative urgently!

+1 My old Shimano were ridiculous in the wet. Swisstop made the world of difference. The pads that came with my new Ultegra calipers are fine in the wet and dry.

Keep the pads and rims clean and free of debris and you should find your wet weather braking performance is not as bad.

Exactly. I use swisstops and they are very good but if you are scrubbing off a lot of speed, and dont have a good surface to work on the pads will be a little less effective. Clean your wheels after a long slog in the wet ( or snow as i did on saturday) and its beneficial to you and your bike. also, clean your pads, as my rear pads recently had a lot of build up that caused inconsistent braking.
