Rear wheel cylinders are most prone to failure, especially the inexpensive cylinders frequently sold online. These are premium cylinders made in the UK which we have found to last longer. These are the cylinders we use in all the cars that come through our shop. You'll pay a little more but save on the labor given the greater longevity for this product.
These are the early Bugeye single piston rear wheel cylinders. Note in the picture below the piston exits on one side (the right side in this photo). Some cars have been upgraded to the later dual-piston rear cylinder. Confirm you are ordering the correct one (note-the later cylinder requires a different back plate)
It is wise to change these in pairs. They come with the rubber boots too.
- 2 wheel cylinders are required for each front wheel (total of 4 wheel cylinders for the front).
- 1 wheel cylinder is required for each rear wheel (total of 2 wheel cylinders for the rear).
- If you discover a leaky wheel cylinder, you should replace the brake shoes and clean the drum with brake clean.
- We recommend you replace your brake hoses as well as the master & slave cylinders. You can purchase them individually, or all together in our Hydraulic Rehab Kit.
When installing these wheel cylinders, it's easy to trap air inside them. The piston pushes out when the e-brake small lever on the cylinder itself is actuated. If this is not done during installation, air can become trapped in the small cavity, thus giving you a notoriously squishy pedal. Be sure to open the hydraulic system and physically squeeze the cylinder together to get the air trapped in that small pocket out.
