Front brakes
Question:
Hi guys, I ‘ve to change my front disc brake rotors on my K1500 Suburban and I’m looking for an after market solution and why not a better performance rotor (easy…) What do you think about Ricambi or SSBC rotors ? Or is there any other company to manufacture rotors for this car ? Any help will be appreciated !! Regards Phil
Response:
Try www.truckperformance.com My father has dealt with them before, was very happy. You don’t say if you have a 2WD or 4WD, or what year you have. This place sells Powerslot rotors, looks like for some of the older models the only way to get them for 4WD is to buy the kit that is the rotors and pads. Raybestos Quiet Stop pads are a nice match with these rotors. 1999 models have a lising for just the rotors on 4WD trucks… – Hide quoted text — Show quoted text – > Hi guys, > I ‘ve to change my front disc brake rotors on my K1500 Suburban and I’m > looking for an after market solution and why not a better performance rotor > (easy…) > What do you think about Ricambi or SSBC rotors ?

My suburban is a 4WD 92 model, and I’ve tried truckperformance but it seems that Powerslot rotors didn’t got any rotors for the 4WD model. Regarding Raybestos, I don’t know anything about them (performance level, quality and so on) Thanks for your answer Phil
Response:
Phil, Yes it’s easy. No, you won’t notice any improvement unless you make repeated high speed stops. There is a TSB for Suburban brakes. It requires the installation of ceramic "Durastop" rear shoes and a new proportioning valve. The difference is night and day. BTW, Raybestos makes some of the best brakes parts you can buy.

Every time I use Raybestos brakes I get black powder all over my rims. I can wash them and it is covered in 3-5 days. I stay clear of them now.

What type of Raybestos pads? They have several different types, and as with all brake pad lines, the cheap ones are messy as hell, the expensive ones are much cleaner. Doc

Response:
Cheap ones I guess. 
They only cost $26. Which ones should I look for? I usually get 6 months out of a set of front pads. 251K on the truck, so I drive it a LOT.

My personal preference isn’t Raybestos but rather Performance Friction pads, available at Autozone for around 50 bucks a set. They aren’t quite as aggressive as some of the Raybestos pads, but are the quietest, cleanest, longest lasting pads I’ve ever used. About 20,000 miles on the front pads on my 1/2 ton which I use as a daily driver. Not a SINGLE squeak or chirp in the past 20,000 miles and the pads are just as thick as they were when new. Virtually no black dust either. Again, this is a personal preference, but performance tests on their website www.performancefriction.com (I think?) empirically verify my observations. Doc

I’ve been using Raybestos pads for the last couple months. I’ve noticed LESS dust on my wheels, compared to GM pads. I have the Raybestos PG Plus pads, $30 a set at Pep Boys. Apparently, the Quiet Stop pads are some of the most dust-free pads around but I’ve had VERY little dust on my wheels. Maybe this is an indication of how long these pads will last, old one had about 24,000 miles on them and were a lot dustier than these… – Hide quoted text — Show quoted text – > Every time I use Raybestos brakes I get black powder all over my rims.

TSB 86-50-20 covers both front and rear brake problems. The issue is that the rear brake shoes are defective and don’t work. This causes the front pads/rotors to wear excessively and greatly increases stopping distances. This can be very noticeable when towing or braking downhill. The front end will also dive severely upon a hard stop indicating that the rear brakes are not working. You may also experience pull when braking, rear drum shudder when braking while backing up, especially when the shoes are wet, and apparent failure of the rear self-adjusters to self-adjust. If you have any of these problems, have your dealer look it up and see if it applies to your vehicle. Trucks get the new shoes, Suburbans also get a new proportioning valve. The text of the TSB follows: Bulletin No.: 86-50-20 Models: 1992-98 Chevrolet and GMC C/K Truck and Suburban Models 1996-98 Chevrolet and GMC G Vans with RPOs JB8 or JD7 Condition: Some owners may comment about the vehicle leading or pulling to either side while applying the brakes or front brake wear not meeting expectations, especially vehicles that have been used to tow a heavy load. Cause: Conditions may be caused by excessive wearing of the font brake material. Improvements to the above conditions can be gained through rear brake material modifications. On Suburban models, the best performance from this new brake material can be achieved with replacing the proportioning valve. Correction: Replace the rear brake shoes with Dura Stop brake shoe kit. On Suburban models (C/K 20906), a proportioning valve must be installed. All other models (C/K, G), no proportioning valve change is required. Use the part numbers listed. Refer to Section 5C2 of the Service Manual.
