davidlwest Posted September 26, 2005 Share Posted September 26, 2005 Hi - Has anybody had a problem with Impreza front brakes heating up and creating a strong smell going downhill in mountains? This is on twisty dirt roads going 20-40 MPH, not terribly steep. Brake pads were just replaced a month ago - maybe a problem with replacement pads - I don't remember this with the old pads...

NoahDL88 Posted September 26, 2005 Share Posted September 26, 2005 down shift, let the engine do the brakeing. its not uncommon for brake fade on long down hill stretches. at high altitudes its even worse cause there is less air to dissipate the heat.

nipper Posted September 26, 2005 Share Posted September 26, 2005 Yes down shift. If the hill is long enough, any brake will start to fade eventually. Never totally rely on the brakes on downhills, otherwise they wont be there when the deer jumps out in front of you. nipper Quote Link to comment Share on other sites More sharing options...
blitz Posted September 26, 2005 Share Posted September 26, 2005 It didn't used to smell, but after changing to new pads, it smells. I think there's a connection there. Either the new pads are curing (good) or burning (bad). Quote Link to comment Share on other sites More sharing options...
nipper Posted September 26, 2005 Share Posted September 26, 2005 How new are the pads, and what brand. nipper Quote Link to comment Share on other sites More sharing options...

The advice about downshifting is good, but what you are smelling is the chemicals from pads or anti squeal materials getting hot. Our mail cars always does this when we change pads because we get them so hot with all of the stops, and of course yours got hot going down the mountain. After a few days it goes away.

Setright Posted September 27, 2005 Share Posted September 27, 2005 New pads still need to burn off some of the chemical bonding agents. Phenolic resins is the correct term, I think. I had the same problem on the Nürburgring recently, braking hard down the hill into Fuchsrore.....only happended the first time, after that the brakes didn't smell.

jamal Posted September 27, 2005 Share Posted September 27, 2005 Do they just smell hot, or can you notice fade? Using the brakes hard can definitely heat them up to the point where they smell. I've had my brakes hot to the point where they smelled a little burnt, but were still working fine. I've also had them fade noticably. If you're already engine braking and you notice the braking ability is reduced, you should probably get a set of better pads. I used the wonder that is the classified forum on nasioc to pick up wrx front and "h6" rear brakes on the cheap. It's a bit of overkill though. Here's a picture of some really hot brakes: Quote Link to comment Share on other sites More sharing options...
wrongturninwv Posted September 27, 2005 Share Posted September 27, 2005 Rotors cut and a good set of Bendix pads is my answer. I live the highest part of West Virginia and have had Subarus for 13 years out here . Nothing but mountians to go up and down on. Go down some hills at 50mph or better and it hair pin curves too,good set of pads and all in how you drive it. Just watch out for the deer,had one leap right over the hood the other night on the way down hill but that did not slow me down a bit. Subaru is like driving a super high class go-cart. lol luv the wifes Outback Quote Link to comment Share on other sites More sharing options...
tcspeer Posted September 27, 2005 Share Posted September 27, 2005 jamal, I have never got mine hot enough to notice fade from the many stops I make on my job, most likely their is some there I just havent noticed. Quote Link to comment Share on other sites More sharing options...
