need recomendations for performance pads & shoes

Post by TranzAm » 22 Jan 2008 22:41

Went to the local speed shop today to buy a set of performance brake pads and shoes, only to find that no one makes them. Some one has to make a semi metalic pad and shoe for our 510's. Does anyone know where I might find a good set for a relitivley low cost? thanks.

Porterfield makes some awsome pads for stock 510 brakes.. my brother got some for his WRX and said they were the best he'd ever used.

I think they charge 70-80 for fronts.. not all the cheap... but still great performance pads. Shoes? I dunno.. maybe some one else will chime in..

cool that will work. just dont know what the difference between the r-4s and the R-4's are. Im guessing the R-4's are a more agressive pad.

Your right, the R-4s is the street/auto-x compound and the R-4 is more of a track day/race compound.

What kind of driving do you do? Race or street. Some compounds grip best when super hot like those on a race track. Likewise the stopping distance is much much longer when cold. Most driving is done on cold to marginally warm brake pads. In a panic situation there's no time to warm them up.

In my quest for the "best" street pad, I have tried a whole range of pads. As Mike said, getting the best cold coefficient of friction, with some reasonable top end stopping has been tricky. Pad materials have come a long way in the last 10-15 years. It would be fun to do a brake test on a 510, with the different materials available.

For sure you want the "softest" pad for street driving, as the lack of cold grip can damn near kill you. The pad I have in my car now was made by Perfomance Friction, called the Z-rated pad. Likely the equivelent of the Porterfield. It has very good initial grip (cold), with a lineal ramp up, to temperature, and would likely stop my car 1/2 dozen times from high speed.

I used to use the so called "green stuff" on the rear of my car, before the disc conversion. I would not sweat it too much if you cannot find a better rear shoe, as the stock rear brakes (in my opinion) are pretty marginal at best. You want them to be coming up to temperature relatively fast, as the rear is getting light under braking anyhow, depending on how much front dive you might have. I used to have a brake shop match the shoe arc to the drum, just kept everything as tight and positive as possible.

This season I am going to try a new pad (not available for stock), so we will see how it works through the temp range.

For your stock system, make sure the wheel bearings are in good shape and tight, minimize pad knock back ( that goes for any system). Use good quality brake fluid, and bleed the system at least once a year, more if the brakes have been hot. Keep the rotors true. Keep the back brakes adjusted up, this minimizes pedal travel, and you can "feel" the brakes better. Also make sure the brake pedal itself is adjusted so that all slop is out of the rod that goes to the master, this minimizes travel also, before things start to happen.

What Nissan/Datsun pads does Performance Friction make? I can't find any ZX pads from them.

Sorry, I guess I should have been clearer. I have an aftermarket caliper on my car, and I suspect Performance Friction does not make a pad for the factory calipers?!
If Porterfield makes a nice "soft" pad, I would try that, based on Gensaiken's recomendation.

Bottom line is don't out-trick yourself thinking you need a race pad. Ask yourself, how many times...in a row...did I slow or stop from 100MPH today.

Then think about when Grama, in her clapped out Buick, cut in front of you..how well do you want those brakes to work RIGHT away.

I run the R4-S on my car (280ZX fronts, 200SX rears), and although I don't have anything to compare them to, they work for me. They lose their initial bite if they get wet though, so keep that in mind. I think Spencer had to give his up for winter driving in Vancouver, but you shouldn't have the same problem.

That is a very good point, Derek. I had Metal Masters in my GTS, and one day, in the pouring B.C. rain, it had to stop suddenly at the Tunnel. I had not used the brakes since home, some 15 Km behind me. It was one of the closest calls I have ever had. Those pads were horrendous. I went back to the factory pad, from Toyota, and they are not bad, good for a couple of high speed stops, and just great in the rain.
