Best Brake Pads for Wet Weather Mountain Biking
Share
It's November on the North Shore. You're dropping into Bobsled and the roots are glazed with rain. You pull the lever early, give it a good squeeze, and... the bike just keeps rolling. Your organic pads have turned into bars of soap. Sound familiar?
If you ride in the rain regularly, sintered or Gravity compound pads are the only real option. Organic pads lose too much bite when wet and wear out 2-3x faster. We're based in North Vancouver. It rains here 8 months a year. Everything we sell is tested in conditions most brands never see.
Why Organic Pads Fail in the Rain
Organic (resin) pads are made from a mix of rubber, glass, and kevlar fibers bound with resin. They work great in the dry. Quiet, good initial bite, easy on rotors.
But get them wet and everything changes.
Water creates a film between the pad and rotor that organic compound struggles to cut through. You lose 30-40% of your stopping power. And it doesn't come back quickly. You have to drag the brakes for a few seconds to boil off the moisture before they start biting again. On a steep North Shore trail, you don't have a few seconds.
Then there's the wear problem. Wet grit acts like liquid sandpaper on soft organic compound. A set of organic pads that lasts 4-5 months in summer can be gone in 2-3 weeks during a rainy BC winter. That's not an exaggeration. We've had heavy riders come back for new pads twice a month in November and December.
Sintered vs Gravity Compound in Wet Conditions
Sintered pads are made from metallic particles fused under high pressure. They're harder, more durable, and much more consistent in the wet.
Where organic pads lose 30-40% of their bite in rain, sintered pads lose maybe 10-15%. And they recover almost instantly. One pump of the lever and they're grabbing. That difference matters when you're committed to a steep line and the trail is running with water.
Our Gravity compound takes this further. It's an organic compound with a high metal content, organic feel and modulation, but with power much closer to sintered. The key advantage: Gravity insulates the braking system. Sintered conducts heat into the caliper and brake fluid, which on a sustained descent can soften the lever and contribute to fade. Gravity keeps heat in the rotor where it belongs. That's the same engineering principle Magura, Trickstuff, and Sinter build their entire ranges around. It's what most North Shore regulars end up running year-round at Loam Goat.
The tradeoff with sintered: better pad durability in deep mud, but more heat transferred into the hydraulic system. Gravity runs quiet to very quiet despite its metal content, the organic compound handles that. For a muddy XC loop where pad longevity is the priority, sintered is hard to beat. For a sustained descent where lever feel matters at the bottom, Gravity's system heat insulation gives you the edge. And they wear rotors a tiny bit faster. But honestly, replacing a rotor every 2-3 years versus replacing pads every 2 weeks is an easy tradeoff.
Does Rotor Size Matter in the Wet?
Short answer: yes. Bigger rotors give you more leverage and better heat management.
A 200mm or 203mm rotor up front provides noticeably more stopping power than a 180mm in the same conditions. The larger diameter means the pad is further from the axle, so you get more mechanical advantage. It also means the heat is spread across a bigger surface, so the brakes stay more consistent on long descents.
If you're a wet weather rider and you're still on 180mm front rotors, consider going up a size. It's one of the cheapest upgrades you can make and the improvement is immediate. Loam Goat stocks rotors in all common sizes.
For the rear, 180mm is usually fine. The rear brake does less work and a smaller rotor saves a few grams where it matters less.
How to Bed In Brake Pads in Wet Weather
Bedding in is the process of transferring a thin layer of pad material onto the rotor surface. It's critical for good braking performance. And it's trickier in the wet.
Here's what we recommend:
Find a flat, paved section. Even a parking lot works. Get up to moderate speed (15-20 km/h) and apply the brake firmly but don't lock the wheel. Repeat 15-20 times per brake. You're looking for a consistent feel and a slight gray discoloration on the rotor.
In wet weather, it takes more repetitions because water keeps washing away the transfer layer. Give it 20-25 stops instead of the usual 15. Don't rush it. Half-bedded pads will squeal and underperform for weeks.
One thing to avoid: don't bed in pads on a trail descent. You need controlled, repeated stops at moderate speed. Bombing down Seventh Secret with fresh pads is a recipe for glazed, underperforming brakes.
Our Wet Weather Setup Recommendation
After years of selling pads to North Shore riders and hearing what works, here's the Loam Goat wet weather setup:
- Front: Gravity compound pads, 200mm or 203mm rotor
- Rear: Sintered pads, 180mm rotor
- Bed-in: 25 controlled stops per brake on pavement before hitting the trails
- Spares: Carry a spare set in your pack during peak mud season. Pads can wear through in a single long, wet ride if conditions are bad enough.
Gravity up front gives you the maximum attack where you need it most. Sintered on the rear saves a few dollars and is more than enough for modulation duty. This combo has been our go-to recommendation for three seasons running and we haven't had a single complaint.

Frequently Asked Questions
Do brake pads work worse in the rain?
Yes, all pads lose some bite when wet. But the difference between compounds is massive. Organic pads can lose 30-40% of their stopping power in rain. Sintered pads lose maybe 10-15% and recover faster. That gap is the difference between a controlled stop and a sketchy moment on a wet root section.
How fast do brake pads wear in wet conditions?
Roughly 2-3x faster than dry. Grit and water act like sandpaper on the pad surface. In a wet BC winter, heavy riders can go through organic pads in 2-3 weeks. Sintered pads hold up much better, typically lasting 2-4 months even in constant rain.
Should I run bigger rotors for wet riding?
If you can, yes. A 200mm or 203mm rotor up front gives you more leverage and generates less heat, which means more consistent braking when conditions are bad. It's one of the best value upgrades for wet weather performance.
Can I switch from organic to sintered without changing my rotor?
Usually yes. Check that your rotor isn't rated "resin only" (some lightweight XC rotors are). Most trail and enduro rotors work fine with sintered pads. Clean the rotor thoroughly with isopropyl alcohol before installing sintered pads to remove any organic pad residue.
What's the best all-weather brake pad?
Our Gravity compound. It's an organic compound with a high metal content, aggressive bite in all conditions, system heat insulation on long descents, and the quiet operation you don't get from sintered. It's what most North Shore riders end up running year-round at Loam Goat. Sintered wins on raw pad longevity in deep mud, but Gravity is the better all-rounder.
Wet riding doesn't have to mean bad brakes. Get the right compound, bed them in properly, and you'll actually look forward to rainy days on the trail. Well, maybe not. But at least you'll stop when you need to.
