#178 of 618 rusty lines and driveshaft
Nov 12, 2009 (9:28 pm)
I climb under my 2003 2500 HD silverado, Durimax Diesel that I bought new to change the oil and look at eveywhere there was a clip on the brake line it was ready to rust through. So I go to the local Auto Parts store to get some brake line. The fittings on my truck are 14mm nuts with either 10mm or 12 mm threads on the nuts, and the line is 10 thousands bigger than 1/4 inch line. Advanced Auto, and NAPA as well as all the other auto part stores have only american standard threads on their brake line pieces. I will get metric inverted nuts then they don't have them and can't get them????Ok, I will get metric! CAN'T they dont have any metric lines,or nuts on 1/4 inch line? You've got to be kidding me!Nor, can they get it??? They have no Inverted fittings on 1/4 inch metric either??? My line is not bubble its inverted??? OK I go to the Chevy Dealer and order the parts--- I can't all their computers and books tell me their is American line and nuts on my truck. The parts guy looks at my line and says thats metric, but nothing listed in computer is metric for 2003,2005,2002 and he can't get it either. So only option I have is to cut off line and re-use old nuts on 1/4 inch line and hope the flange tool compensates for the 10 thousands line size difference and what if I strip one I'm in a world of hurt. Is there anyone else that has had this problem? I can't be the only one in America with this problem and what did you do?

I have not heard of this issue, we have 4 GMC pickups in the family and not had this issue, we have had our brakes, and brake line rusting, but not the metric/american issue. You may review some of these threads... #125 of 178Re: Rusted Brake lines, 2003 GMC 50K miles [barnowl3] by ttaupier1, ..........in the : Forums/Pickups/Chevrolet Silverado & GMC Sierra/Chevy Silverado and GMC Sierra Brake Problems
There are several links and different guys that needed to find the solutions to similar problems (rusty lines). To tell you the truth, I am very surprised this is the first time, we have seen or heard of this, knowing the vehicles are mostly manufactured in a Metric based countrys, and serviced in the USA, ...almost sounds like there was a daily supply issue and someone at the factory came-up with a short time fix... Yikes...
keep us posted..
#180 of 618 Do I need a brake pad replacement tool
Nov 21, 2009 (8:37 am)
I need to replace the rear brake pads on my '99 Silverado, and was told that I may need a special tool to compress the calipers. Will a regular 'C' Clamp not work. If not what of kind of tool is this and is it easy to get?

Yep a big C clamp would work.

Important: Use denatured alcohol to clean the outside surface of caliper boot before installing new brake pads.
1.If you are installing new brake pads, use a C-clamp in order to compress the piston to the bottom of the caliper bore. Use the old brake pad, a metal plate or a wooden block across the face of the piston in order to protect the piston and the caliper boot. Important: Use a small flat-bladed tool and lift the inner edge caliper boot next to the piston to release any trapped air.
2.Ensure that the piston boot is below the level of the piston face.
3.Install the brake pad retainers to the caliper bracket. Important: Ensure that the wear sensor is positioned at the leading edge (upward) of the inner pad during forward wheel rotation.
4.Install the brake pads over the brake pad retainers and onto the caliper bracket.
5.Install the tire and wheel assembly.
6.Lower the vehicle.
7.With the engine OFF, gradually apply the brake pedal to approximately 2/3 of it's travel distance.
8.Slowly release the brake pedal.
9.Wait 15 seconds, then repeat steps 7-8 until a firm pedal is obtained. This will properly seat the brake caliper pistons and brake pads.
10.Fill the master cylinder reservoir to the proper level with clean brake fluid.
11.Burnish the pads and the rotors.

Hey John, I have done a lot of brakes in my day, and nearly every rear disc caliper, from a 63 Maserati "Mexico", 2002 Honda accord, to a 2003 Jeep Grncheke, to a 2003 GMC 1500 pickup, I have always had to screw the rear calipers in as they are being compressed...hence the special tool. This is based on 25 years of doing about 40 brake jobs (friends and family). I have used a c-clamp, however the screwing in of the caliper piston is very key to the compression process. I have never had a special tool...however i did find this excerpt from another Car help page....
was unaware that nearly all modern vehicles w/rear disc brakes NEED turned in, like a screw. so i ruined a clamp and the calliper trying to figure it out the special tool purchase is not required in most cases because most auto parts stores offer free tool rentals to promote the sales of auto parts, and the tool they offer is usually better than the one most people are willing purchase due to expense probably in the upwards of $50. there is a cheap tool option 3 to 4 bucks kinda looks like a cube w/ a 3/8 ratchet drive hole on each side for a extention to fit to your ratchet. and it has different sized/shaped pegs at the corners of each side to make it more compatible with other vehicles, efficient but difficult to use and i really dont suggest it either but ive used one and it did get the job done.

I have the same issue and I found out that it is the ABS kicking in. This is caused by rust and the sensor and tone wheel in the bearing housing on one or possibly both front wheels.
#185 of 618 2007 chevy silverado rear brake shoes
Nov 28, 2009 (6:22 am)
New to this blog, but looking for information on replacement of rear brake shoes on my silverado. Apparently GM had gone back to drum brakes, and upon inspection noticed that there is a big sort of u-clamp or u-shape pin going across both brake shoes to hold in place. Any ideas on how to reinstall easily or special tool suggestion. I changed one side and wow what a hard time it was getting the rod back in place.

On a 2001 1500 is there a safe way to unhook the ABS brake system?
Nov 30, 2009 (3:45 pm)
I have had this brake problem with my 2001 GMC Sierra since I purchased the truck. They have cleaned whatever it is they had to clean and given it back to me only to have the same problem around 6 months later. I have had this done over 10 times and have never yet received a recall notice on this problem.
