Question about 2003 Chevrolet Suburban 1500
First check your power steering fluid. the system that this truck uses is called hydro boost and is fed hydraulically through the power steering pump. if it is low on fluid, it will have an affect on the ease of the brake pedal. the other youre going to need to have your charging system tested if you havent already. if you have what were the results?

I find this about this problem... This is what they do: Document ID# 1633606 (other Bulletins) ABS Light On, DTCs C0265, C0201, U1041 Set and/or Loss of Communication with Brake Module (Reground EBCM Ground) #04-05-25-002B - (Mar 23, 2005) 2004-2005 Buick Rainier 2002-2005 Cadillac Escalade, Escalade EXT 2003-2005 Cadillac Escalade ESV 1999-2005 Chevrolet Silverado 2000-2005 Chevrolet Suburban, Tahoe 2002-2005 Chevrolet Avalanche, TrailBlazer, TrailBlazer EXT 2003-2005 Chevolet SSR 1999-2005 GMC Sierra 2000-2005 GMC Yukon, Yukon Denali, Yukon XL 2002-2005 GMC Envoy, Envoy XL, Sierra Denali 2004-2005 GMC Envoy XUV 2002-2004 Oldsmobile Bravada This bulletin is being revised to update the parts information and add 2005 model year vehicles. Please discard Corporate Bulletin Number 04-05-25-002A (Section 05 -- Brakes). Condition Some customers may comment that the ABS light is on. Upon further inspection, DTCs C0265 and C0201 may be set in the brake module. It is also possible for DTC U1041 to set in other modules. There may also be a loss of communication with the brake module. Cause A poor connection at the EBCM ground is causing unnecessary replacements of brake modules. Important: The EBCM Ground is different for each application. Refer to the list below for the proper ground reference: ? Midsize Utilities = Ground 304 ? SSR = Ground 400 ? Fullsize Trucks and Utilities = Ground 110 Correction DO NOT REPLACE THE BRAKE MODULE. Perform the following steps to improve the connection of the EBCM Ground: 1. Remove the EBCM Ground. The EBCM Ground is located on the frame beneath the driver's side door. If multiple grounds are found in this location, the EBCM ground can be identified as the heavy (12-gauge) wire. 2. Clean the area, front and back, using a Whiz Wheel®. 3. Install the ground, then the washer and then the bolt to the frame. Important: It is important to use the bolts, washers and nuts specified in this bulletin. These parts have been identified due to their conductive finish. 4. Install a washer and nut to the backside of the frame. Tighten: Tighten the nut to 9 N·m (79 lb in). 5. Cover the front and back side of the repair area using Rubberized Undercoating.
